Doesn't connect to the world of tanks server. Why are World of Tanks servers unavailable?

“Unable to establish a network connection in WoT. The server may be unavailable or your network connection settings may need to be checked." Does this message sound familiar to you? Then this is the place for you. This message can occur for a hundred reasons. In this article, I will try to reveal the main ones.

At the very beginning, I would like you to clearly understand the decoding of this message. Although there is nothing special to understand here. Tanks swear that you either do not have the Internet, or the client for some reason cannot find a connection to the game server. That is, you launched the client, which in turn tries to go online and search for its server at a pre-known IP address, but the server does not respond to it and accordingly an error message is displayed. Next, for clarity, let’s look at exactly how the procedure for connecting to the game server goes:

Now, I hope, everyone understands the scheme by which it is necessary to find the problem that prevents the client from connecting to the server. Let's move on...

By the way, in more detail about the connection router -> provider -> game server I told in the article, because... this equipment largely affects the “lags and freezes” in the game. If you have a very high ping, then you are welcome to read.

How are we going to fight?!
BUT, the very first step will be entering the wargaming portal itself dedicated to tanks. Welcome! What if some work is currently going on on the servers? The developers inform you about this in advance and even describe the time during which the servers will be unavailable, and they post all this on their website, so don’t be shy and go in.

Next we follow the “scheme”. After the game client, the first obstacle is the firewall. Disable it (instructions) and try to enter the game. Happened? Congratulations! Play with the firewall disabled or read the article below.

So, we have identified the culprit. Now you need to open the ports and create rules for this little thing (Windows firewall). But first, let's do the same thing only in automatic mode.

Let's go download .bat file from wargaming server:

It's not a virus, don't worry. You can open it with Notepad++ and make sure. Here are its contents:

@ECHO OFF set Arg1="%~d0%~p0WorldOfTanks.exe" set Arg2="%~d0%~p0WoTLauncher.exe" IF NOT EXIST %Arg2% GOTO errorwotl netsh firewall add allowedprogram %Arg2% WoTLauncher enable all netsh firewall add portopening udp 20010-20020,32800-32900,12000-29999,5060,5062,3478,3479,3432,30443,53,6881-7881,1900 wot-udp enable netsh firewall add portopening tcp 80,443,5222,52 23.6881- 7881 wot-tcp enable IF NOT EXIST %Arg1% GOTO errorwot netsh firewall add allowedprogram %Arg1% WorldOfTanks enable all chcp 1251 >NUL set text_y="WorldOfTanks.exe" and "WoTLauncher.exe" successfully added to the firewall exception list. chcp 866 >NUL echo %text_y% GOTO exit:errorwotl chcp 1251 >NUL set text=The file "WoTLauncher" could not be found. Make sure the file is located in the game client folder. chcp 866 >NUL echo %text% GOTO exit:errorwot chcp 1251 >NUL set text_l="WoTLauncher" was successfully added to the firewall exception list. The file "WorldOfTanks.exe" could not be found. Make sure your game client is updated to the latest version. chcp 866 >NUL echo %text_l% :exit PAUSE

Now launch the game and try to connect to any server. So how? Works? We defeated the message “Unable to establish a network connection in WoT”, HURRAY! Let's go play and don't worry about anything else! If it doesn’t work, then we’ll go do everything manually.

In order for the message “Unable to establish a network connection in WoT” to no longer appear, it is necessary that some ports are open in the firewall for the launcher and the game client, here they are:

For WorldOfTanks.exe:
— UDP ranges from 32 800 to 32 900, from 20 010 to 20 020 and UDP port 53;
— TCP ports 80, 443.

For voice chat to work, it is also necessary for WorldOfTanks.exe to open the UDP range from 12,000 to 29,999 and ports 5060, 5062, 3478, 3479, 3432, 30443.
For text chat to work, WorldOfTanks.exe must open TCP ports 5222 and 5223.

In addition, you can allow WorldOfTanks.exe to use the UDP protocol and the TCP protocol on any ports in both directions, thus allowing the firewall to pass any packets to any addresses for the game client.

For WOTLauncher.exe need to open:
-UDP ports 53, 6881, 1900.
-TCP ports 80, 443, 6881.

Well, how did it work out? If YES, then I’m happy for you. Well, if not, then don’t despair and read on...

The next obstacle to connecting to the server is the antivirus. If you don’t have it, then skip this paragraph.
Try adding the game folder to the trusted zone of your antivirus. BUT before that, check your computer for viruses.
Everyone’s antivirus is different, which is why the development team wrote a whole book with instructions for you and me, the link to which I provide here. (Many thanks to them for their titanic work)
How to add a game client to the antivirus exclusion list.

You can also (but not necessarily) add a list of server IP addresses.

Servers RU1–RU9:
92.223.19.1 - 92.223.19.255
92.223.8.1 - 92.223.8.255
92.223.1.1 - 92.223.1.255
92.223.12.1 - 92.223.12.255
92.223.18.1 - 92.223.18.255
92.223.4.1 - 92.223.4.255
92.223.10.1 - 92.223.10.255
92.223.14.1 - 92.223.14.255
92.223.36.1 - 92.223.36.255
185.12.240.1 - 185.12.240.255
185.12.242.1 - 185.12.242.255
Range of addresses required for the launcher and portal to work:
185.12.241.1 - 185.12.241.255.
Ranges of server addresses required for voice communication:
64.94.253.1 - 64.94.253.255
74.201.99.1 - 74.201.99.255

In some cases, disabling the antivirus and firewall does not solve the problem - the ports remain closed.

Here either the network connection is faulty, or herself Windows already moves the horses By the way, this may cause lags and slowdowns in the game. How to deal with them is written. Now let's try to reset the TCP/IP network settings and all sockets from the Windows command line using the command "netsh winsock reset".

Launch the command line:

– For Windows XP: Click Start > Run. In the window that opens, enter cmd.exe and click OK.

– For Windows Vista and Windows 7: click Start, type cmd in the “Start Search” field, right-click on the cmd.exe file and select “Run as administrator.”

– For Windows 8: on the desktop, press the key combination Win+X. In the menu that opens, select “Command Prompt (Administrator).”

Enter the command at the command line netsh winsock reset and press Enter.

Now all that remains is to restart the computer.

How are you doing with the message “Unable to establish a network connection in WoT”? Victory? HURRAY!!!Keep it up! Well, now we can go into battle! Good luck on the battlefields, dear tank men and women!

Share in the comments which method helped you...

One of the most popular operating systems for mobile devices today is Android. It has a number of huge advantages over its competitors and is an almost undisputed leader. However, relatively recently, reports of problems with one of the main services of Android devices, namely Google Play, began to arrive. When logging in, the application began to display an error: “A reliable connection cannot be established.” The system help provided by the suppliers does not help. Then how to solve the problem that has arisen?

Fast and easy

To begin with, we will present a method that will not require you to perform any complex or dangerous operations with the gadget. The simplest solution to the “Unable to establish a reliable connection” error is based on system settings. You just need to check the system date and time in your Android device. They must coincide with the real ones within one minute. This is due to restrictions on the validity of program certificates. If the date is incorrect, the phone will consider that the validity period of the certificate has not yet arrived or has already passed.

Clean up

This method is suitable for those who do not have any important data saved on their device. Although, in fact, you can always transfer photos and videos to your computer and download applications again, especially if you have synchronized your data with your Google account. Then, even if you reinstall, all application data should be preserved. So, there are two ways to resolve the “Unable to establish a reliable connection to the server” error.

Reset your phone to factory settings. You can use special programs offered by application developers, or find instructions that are suitable specifically for your Android device model. After all, each manufacturer has its own tricks and protection mechanisms.
Add a new account. As you understand, old data will not be copied to new versions of applications, but you can avoid problems with transferring other information that needs to be saved when completely wiping the phone. To add a new account, do the following:

Download the AddAccount application via your computer or phone browser.
Write the downloaded apk file to the initial directory on your phone's memory card.
In a standard browser, enter: content://com.android.htmlfileprovider/sdcard/add_account.apk.
Follow the link.
Launch the program. Enter your email on Google and click Add Account.
If you are prompted with an incorrect password message, enter it and continue. That's it, you have a new account.

In addition to drastic methods, there is a less dangerous solution. “A reliable connection to the server could not be established” is an error that is related to the temporary and personal data of the application. Therefore, possible solutions to the problem situation can be looked for in another area.

Freedom

Statistics show that sometimes problems with Google Play can be related to other applications. In particular, the Freedom program. She is responsible for purchases in the application we are considering. The problem where you can't establish a reliable connection to the server can occur if you downloaded and uninstalled Freedom without first forgetting to turn it off. As is clear from the above, to return everything back, download and install this utility. After that, enter it and stop it by clicking on the Stop button. Then you can safely delete it.

Internet

If the previous method did not help you, you should check your Internet connection settings. Problems like “Cannot establish a reliable connection to the server” may occur with some providers, but incorrectly. Before trying to solve the problem using this method, try opening Google Play by connecting to another Internet source. If you still need to return to the initial option, download the Set DNS application. Set the DNS address to 8.8.8.8. This should help in cases where Wi-Fi is used to connect to the Internet. In any case, first try to test your device on a different connection.

Another possibility for why a reliable connection to the server cannot be established is that the server may be blocked. In order to test this method, you will need superuser rights on your device. Open Explorer and find the file /system/ect/hosts. We need to open it with any text editor. By default, the file should only contain - 127.0.0.1 localhost. We delete any remaining data.

YouTube

The last method to solve the problem lies in additional programs. It is assumed that the user cannot log into Google Play due to incorrect addressing settings in the Google account.

A utility pre-installed on many Android devices for viewing videos from YouTube (or any other program that uses a Google account for registration) will help you cope with this problem. The bottom line is that you just need to launch the application and go through it to your GMail account.

other methods

And finally, it is worth mentioning two more extreme measures. The first of them is “Hard Reset”. Complete device reset. To do this, go to the application menu, select "Settings" - "Backup and reset". After that, in the last window, click "Reset". And delete everything. After which the device should return to its original state. You will have to download all the programs again and set up an account.

Flashing. Update the operating system or reflash the device. The second option is undesirable, since after it you may well be denied warranty service. It's best to just update the OS. Many manufacturers try to independently correct errors that occur to users.

That’s probably all that we could tell you and advise you to do when the error “Unable to establish a reliable connection to the server” occurs. We hope our article helped you.

Stable and fast access to the World Wide Web is not a guarantee that you will be able to freely visit your favorite Internet resources. The error “Cannot connect to the site” often appears at the most unexpected moment.

The essence of the error is that websites stop opening on a computer or on all devices connected to one router, although there is a connection to the Internet. Let's talk about what could be its cause, how to identify the culprit and what measures to take to eliminate it.

No access to all sites

Errors opening websites occur for many reasons. The first group includes situations when the browser cannot access any Internet resource. This group is more common and its causes are more varied than in cases where only certain sites do not open.

Reasons for lack of access

Failure of the network settings of a PC or router (can be caused by the user or software, including malicious software).
Damage to components of the OS network subsystem (this may be the result of user actions, operating system failure, infection and deletion of files of this structure by malware, blocking or deletion by an antivirus).
Incorrect firewall (firewall) or parental control settings (the browser is denied access to the Internet).
Very low speed or interruptions in the Internet connection.

Connecting to the network through incorrectly working or low-speed proxy servers and VPNs.
Incorrect settings or browser crash (including installation of crooked extensions and user scripts).
Activity of malware (in addition to changing network parameters and components, the virus can indirectly block the loading of sites).
Problems on the Internet provider side.

How to figure out the culprit

An analysis of the events that preceded it will help you think about the culprit of the failure.

If before the error occurred:

any actions with the router: replacement, repair, firmware update, changing settings, etc.;
changing the network connection parameters on the PC (for example, new DNS addresses were registered);
installation or removal of programs that interact with network structures (Internet accelerators, traffic analyzers, 3G/4G modem applications, etc.);
manual or software cleaning of the system from garbage, optimization, removing “viruses” using anti-virus utilities, editing the registry, changing group policies,

the most likely reason is incorrect network settings or damage to network components.

If before the failure there were:

installing or removing a firewall or anti-virus program with a built-in firewall;
changing firewall settings;
installing or reconfiguring parental controls;
the appearance of messages about the insecurity of the network connection with a proposal to strengthen protection,

The culprit is most likely an antivirus, firewall, or parental control tool.

If the event is accompanied by:

spontaneous pop-up advertisements;
violation of system functions;
errors when performing normal operations (opening a folder, copying, etc.) that did not exist before;
antivirus program alerts;
loss of access to electronic wallets and online accounts that you used on this PC;
other unusual phenomena that have not been observed before,

The reason is most likely a viral infection.

What to do next

The procedure for diagnosing and troubleshooting the failure below covers all of the listed causes. If you have an assumption about a specific culprit of the problem, you can perform only those actions that are suitable for your case. If the previous one does not help, move on to the next one.

Reboot your router. Check your Internet connection settings, black and white lists of sites, DNS addresses. If the specified DNS is unknown to you, enter the addresses of your provider or Google instead.

Check your network connection settings on your PC. The default gateway must be specified. DNS server addresses (if not assigned automatically) must match the IP of the default gateway, belong to your Internet provider, or be public.
If you use a VPN or proxy to access the global network, disable them.
Make sure your Internet connection is stable and the connection speed is sufficient, using, for example, this service.
Reset your network settings. To do this, launch the system application " Options", go to " Network and Internet" and on the right side of the window click the button " Network reset" Next click “ Reset now" This action will reinstall the Ethernet and WLAN adapters and restore all network components to their original settings. After completing the reset operation, the computer will restart.

Temporarily disable your firewall or firewall, and parental controls if you have them. To disable the Windows 10 firewall, run " Options", open " Update and Security» – « Windows Security" On the right click " Firewall and Network Security" In the Defender Security Center window that opens next, click on the connection marked as “ Active" Next, move the firewall slider to the " Switched off».

Check if the problem occurs in other browsers. If it is present in only one, most likely the reason lies within the browser itself. Check its Internet connection settings (if you do not use proxies and VPNs, but they are specified in the browser settings, delete these entries), disable extensions and user scripts, . If all else fails, export your bookmarks and reinstall your browser.
To exclude the active influence of running programs (including malicious ones) with network support. If access to sites is restored, the reason is in the programs. All that remains is to find which one. However, if the failure is caused by changes made to the system, this will not help to identify and remove them, since they remain in effect even without the presence of the programs that created them. To deal with changes, use the following method.
on the day when sites opened without errors.

Scan the disks with an antivirus.
If the problem occurs on all devices connected to your Internet provider's network, and vice versa, does not occur when connecting to another, call the provider's support service and follow the recommendations of the consultants.

No access to individual sites

Causes

Lack of access to some sites may be caused by most of the reasons listed above. But there is one nuance here - you can make an assumption about the culprit of the failure based on the topic of inaccessible content.

For example:

There is no access to torrent trackers and other similar resources that are prohibited in your country. The reason is blocking by the provider or a higher supervisory organization. According to the rules, a placeholder page with the menacing inscription “ The site is blocked by decision...", but sometimes the error " Can't establish a connection to the site" By the way, sometimes innocent resources, such as Google services, are targeted.
Pages with adult themes, VK and your favorite online game do not open. The probable reason is blocking by parental controls, firewall or DNS with content filtering function. Sometimes in such cases, more sophisticated methods are used - blocking through the Hosts file and so on, which I will talk about later.
Social networks, email and anti-virus resources, and search engines do not open. This picture is typical for viral infection.

What to do

In case of inaccessibility of individual sites, the same diagnostic methods and solutions are used that are used for problems with access to all. But with an amendment: - your allies, not enemies.

And separately about blocking methods that malware uses. To unblock access to a site, simply removing the malware is often not enough: along with it, you need to remove the changes it made to the system.

Hosts File

To put it simply, the file %windir%\System32\drivers\etc\Hosts is a local DNS service. It serves to tell the computer which IP addresses to look for specific sites whose names are listed in this file. If you write in Hosts that the ABC.com website is located at 127.0.0.1, then the computer will look for it not on the Internet, but on its disks. And since it won’t find it, it won’t be able to open it in the browser.

By the way, viruses sometimes hide from the user the entries they have made in Hosts. About methods of concealment.

Hosts is a text file without an extension. To remove a blocking entry, open it in Notepad or a notepad replacement program and simply delete the unwanted lines. If after editing the file is saved with the .txt extension, remove the extension.

There is a class of malware that can rewrite DNS addresses in the network settings of a PC and router. If you notice unfamiliar DNS on your devices, enter the provider or public addresses instead.

Static routes

A static (permanent) route is a hard-coded path for web traffic to follow from one network node (for example, your computer) to another (a website on the Internet). Accordingly, if the route is set incorrectly, the site will not open. The operation of this mechanism is described in more detail in the above.

To find out if your PC has persistent routes, run the command prompt route print

To delete all routes, follow the other instructions: route -f

Assigned Tasks

A scheduled task is an instruction that the operating system executes according to a schedule or when an event occurs (for example, after Windows boots). Such tasks can be created by both users (via the Task Scheduler) and programs installed on the PC.

Assigned tasks are stored in folders %windir%\tasks And %windir%\system32\tasks in the form of text files: one task – one file. A file created by malware can usually be easily identified by a meaningless name made up of a string of numbers and letters, such as sgjed4jlui.job. In addition, the date of its creation, as a rule, coincides with the date of the problem with opening sites.

Before deleting suspicious jobs, it is advisable to create backup copies of them in case of a possible error.

Malicious proxies

Proxy servers are intermediate nodes that pass the network traffic of a computer (router) through them before exiting to the World Wide Web and back. In addition to useful tasks, such as protecting traffic or masking IP, they can be used by attackers to redirect the user of an infected machine to phishing web pages, as well as to block access to individual sites.

Proxy servers (if used on a PC) are registered in the system registry, namely in the sections HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings And HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings

The parameter is called ProxyServer.

To remove a setting from the registry, right-click on it and select " Delete" The changes will take effect after you restart your computer.

The World of Tanks game does not start - the "play" button does not work.

One of the common problems logging into World of Tanks is related to the “Play” button in the launcher. It is this button that must be pressed every time you start the game. But what to do if it doesn't work. You click and nothing happens - World of Tanks does not start? To answer this question, we have collected the most common errors when logging into WOT and described solutions for each problem. Let's look at each one in order, starting with the launcher not working.

If you cannot enter World of Tanks when you enter the game, you need to open the launcher, click “play” and see what happens. If you wait for a long time, the problem with logging into WOT is often hidden behind the inability to connect to the Wargaming servers serving your chosen cluster. In this case, you should check for a problem on your PC, namely:

Is the port through which data is exchanged between the World of Tanks client and the server blocked by your firewall?

If yes, you need to add an exception to the firewall. If this is a regular Windows firewall, just go to the control panel, select "Firewall" and add the file worldoftanks.exe, as well as the launcher executable file wotlauncher.exe to the list of exceptions. You can do this by double-clicking on the “Firewall” icon and going to the “Exceptions” tab, then adding there the above files with the .exe extension from the folder with the World of Tanks game.

Setting up the World of Tanks launcher

Is the application (game) blocked by your antivirus?

If you have installed anti-virus software and have not configured it properly, by default all connections from previously installed programs, including the World of Tanks game, will be blocked. To unlock, add an exception in the control shell of your antivirus (Kaspersky, Dr.Web, Nod32, Eset and others) according to the principle described for the Windows firewall (above).

Mods for World of Tanks are used

Very often, mods can cause the "Play" button in the World of Tanks launcher to not work. Usually, even the best and most time-tested mod fails, especially after its update, which was released immediately before the release of the next patch for WOT. Often, mod developers are in a hurry to release a release that supports a new update for World of Tanks, creating a patch for the mod based on a test version of the game. Using such a “quick” update for a popular mod leads to problems with logging into the game both after the release of the next version of World of Tanks, and after the release of micropatches, 1-2 weeks after the main release.

I press the "play" button and it doesn't go into World of Tanks

To check whether the use of modifications interferes with entering the game, disable them for a while. To do this, just rename the res_mods folder and restart your PC before attempting to log in.

Can't log into World of Tanks: I click "Play" and it doesn't log in

Among the problems with the "Play" button, the second place is occupied by errors related to the Internet connection. Check this category of game login errors using our instructions:

Find out what IP address is used when connecting your PC to the Internet, static or dynamic?

With a static IP address, you are allocated the same address every time you connect to the Internet, and it will be credited to you when you log into World of Tanks. If your static IP address is banned in tanks, every time you try to click on the "play" button in the launcher, you will not be able to connect. To solve this problem, contact your provider with a request to replace the static IP address assigned to you with another one. Some providers charge a fee for this service, while others offer it free. Occasionally, replacing an IP address may require a specialist to visit your home. Even more rarely, this service is not provided at all.
In the case of a dynamic IP address, problems are also observed when the launcher does not enter wot when clicking on the “play” button. This happens when you are assigned an IP address banned by Wargaming when connecting to the Internet. This does not mean that you were banned, someone else playing under this dynamic address in World of Tanks was banned by IP. To solve this problem, simply reconnect to the Internet (disconnect and connect again).

Solving the problem with the "play" button in World of Tanks

Not included in World of Tanks

In addition to the problems described above related to your network or Internet connection, as well as your PC settings, there is a category of problems related to the game itself. Let's consider these errors when logging into World of Tanks:

You updated the game and some files were not updated. Error during update.

If after the update you cannot enter the game, and after clicking “play” the launcher freezes for a long time, then the World of Tanks update was unsuccessful. The game will not always tell you about this. However, when connecting, the server will definitely check whether the hash of the client files installed on your PC matches the current game update. If even one file differs by even 1 byte or is missing, the server will not allow you to enter World of Tanks and will send a command to the launcher to try to update again.

Solving the problem with the game not working

The launcher will again not be able to update, and the game will freeze when you click on “play” and here’s why: some directory or separate file (less often many files) in the game folder is not writeable for the current Windows user. That is, the user under whom you logged into Windows to play World of Tanks cannot overwrite old files for some reason. There may be several reasons:

the user does not have enough rights to control the computer;
the user's rights have been limited by another user;
the user himself has limited the rights to the World of Tanks game files, intentionally or not;
The antivirus manages files at its discretion on your PC.

Each of these points needs to be checked separately and find out whether the update is causing problems when launching World of Tanks through the launcher.

What to do if World of Tanks doesn't work

The simplest solution to the problem when the game does not enter can be to reinstall World of Tanks. Don't be afraid to erase all files to make sure they don't interfere with entering the tanks. The client version of WOT that you install on your PC does not contain any personal data that may be lost when you uninstall World of Tanks, with the exception of files with your replays and mods you previously installed. We have already found out about mods - it is better not to dwell on them if you want to solve a problem with the game. Feel free to reinstall the game, it usually takes about half an hour.

If reinstallation does not help, there is a high probability that the problem with the “play” button is related to the network or Internet connection (solution above).

World of Tanks freezes when entering the game

Particular attention should be paid to the drivers used for the video card and the availability of a license for the operating system. The error I click on the play button and it doesn’t open can be caused by a lack of a Windows license, as well as outdated drivers for your video card. To solve these problems, start by updating the drivers for the video adapter by going to the manufacturer’s website, downloading from there and installing the latest version of drivers that corresponds to your operating system and its bitness (32 or 64 bit). To solve problems with Windows, it is recommended to purchase a license (at your discretion). This will save you from most potential problems with logging into World of Tanks and the launcher.

When registering in the game client, the following message may pop up. What should you do first?

Actions

1.You must disable the firewall and repeat the login procedure.
2.Then follow these steps step by step:

Download the archive you need from the website:

Unzip, copy the bat file and put it in game root directory(for example, C:\Games\World_of_Tanks) and run it as administrator.
Launch the game and try to connect to any server again.
It is necessary for the Launcher and the game client to antivirus/firewall ports were opened:
For WorldOfTanks.exe:

UDP-ranges with 32 800 By 32 900 , With 20 010 By 20 020 And UDP port 53;

TCP-ports 80 , 443 .

For voice chat to work, you also need to WorldOfTanks.exe open UDP-range with 12 000 By 29 999 and ports 5060, 5062, 3478, 3479, 3432, 30443 . For text chat to work, you need to open WorldOfTanks.exe TCP ports 5222 And 5223 . Additionally, you can allow WorldOfTanks.exe UDP protocol And TCP protocol on any ports in both directions, which will allow the firewall to pass any packets to any addresses for the game client.

3.You need to add the game folder to the trusted zone of your antivirus. Before performing this procedure, you must first do a full scan of your computer for viruses.

4.Add the range of our servers to the list of trusted addresses (optional).

There are quite a lot of requests in the comments asking for help in solving the problem when there is no connection to the World of Tanks update server. There are three simple solutions which we will tell you about below.

Problem connecting to the update server

When it is impossible to connect to the WOT update server, use one of the following instructions to solve the problem, download updates and enter the game:

Solution

Option 1

To solve the problem when it fails, you need to do the following. First of all, make sure that your Internet is working properly. Then restart your computer and turn off the internet if you are getting it through a router or router. That is, your network card or modem must be disconnected from power: the network card will turn off itself when you restart the PC, and the modem, router, router or other connector is usually disconnected from power manually. This way we are guaranteed to reset your current Internet connection and connect again. After reconnecting to the network, the blocking of access to WOT updates disappears. This option usually fixes the connection issue for users with a dynamic IP address.

If you are unable to connect to the update server after completing this procedure, try the other options below.

Option 2

Having tried the first option above, we do the following. You need to go into the settings of your network connection and change the available DNS server to a new one. In Windows 10 this is done as follows:

Go to settings (Start - Settings)
Network and Internet
Ethernet
Call up the properties of the adapter through which you access the Internet. If wired, then “Ethernet”, otherwise “Wireless network”. This is done by right-clicking on the icon.
We open the properties of the protocol "IP version 4 (TCP/IPv4)" also through the right mouse button.
Place a dot next to “Use the following DNS server addresses” and enter if not, otherwise replace the DNS server with 8.8.8.8. This is Google's DNS server. The second one we enter is the Yandex DNS server 77.88.8.8.
Save by clicking on the “Ok” button.

For convenience, we have created graphic instructions for you:

After completing the steps described above, the connection to the World of Tanks update server will occur through the generally accepted open policy of access to resources on the Internet provided by leading search engines. This will eliminate the problem with the unavailability of World of Tanks updates.

Option 3

If there is another option to solve the problem with WOT. Most often, after the release of the next patch, servers provide access for downloading to those players who are the first to try to download and to those who have a high-quality Internet connection. If you don't fall into the first category and don't have a high-quality network connection by modern standards, you'll just have to wait. Yes, you got it right. Once again: wait until the majority of players download the new patch, after which access to the update servers will be open to you. This filtering was done due to the fact that the number of simultaneous connections to the World of Tanks data center during the release of updates is off the charts. In these conditions, priority is given to players with fast Internet, who will not wait in line for a long time to download the patch. Be patient and if everything is really fine with your Internet, after 6-12 hours from the moment the update is released, access to the WOT servers will be open to you.

If a message appears on the screen while working with the program "Unable to establish a connection to the server.", follow these steps:

1. Check if your computer is infected with the Kido worm

Read the article about the symptoms of infection and methods of treatment How to fight the Net-Worm.Win32.Kido network worm .

2. Check Internet access

Check if it's available Internet by opening in the browser Internet Explorer website Kaspersky Lab. If access to Internet no, then contact your provider for more information. Please try to activate the application again after you have restored access to Internet.

3. Configure Firewall correctly

If you have installed on your computer Firewall, then make sure that in the settings Firewall there is an allowing rule for the process avp.exe.

Firewall (firewall) designed to ensure the security of your work on local networks and the Internet. Firewall is a software package that checks data transmitted via the Internet or local network, and, depending on the parameters Firewall(direction, transmission protocol, destination addresses and ports), blocks or allows this network activity.

4. Check the system date on your computer

You can learn how to check whether the system date is set correctly on your computer from article KB3508.

5. Try activation again in an hour

6. Contact Kaspersky Lab Technical Support

The problem of connecting to the update server, as players note, occurs quite often, and therefore requires a quick solution.

There are three most common solutions to this problem.

Solutions to the problem with the World of Tanks update server

No Internet connection. First, you need to make sure that your PC is connected to the Internet. If everything is connected, but does not work: restart the computer, router, unplug the cord. You can also go into the Internet settings and set a “dynamic IP address” there.
The previous method did not help, follows the scheme:

Go to Network and Internet settings.
Ethernet.
Calls up the properties of your current connection.
Open the properties of the “IP version 4 (TCP/IPv4)” protocol.
Check the box “Use the following DNS server addresses.” If there is nothing there, enter “8.8.8.8” in the first field. In the second - “77.88.8.8.
Save the settings and click “OK”.

Last 3 option, although very rare, can occur when servers are seriously overloaded when too many players are trying to install updates at the same time. In this case, there is only one option - wait a little, and the problem will solve itself.
