Hello, all,
Due to the large amounts of threads that players are creating I decided to place the solution here for easier finding. Credits go to hshmt for the solution. Source. To make things even easier I've also added screenshots for each step in spoilers. Please note these steps are for Windows operating systems, if you are using Mac some steps may be different for you.
WARNING: Be sure to backup your WoTLauncher.cfg before attempting step 3.
Step 1.
Go to your World of Tanks installation directory. For me it's found in D:\Games\World_of_Tanks (this may be different for you).
Step 2.
Open the file called WoTLauncher.cfg. Note you may get an error saying Windows can't open this file like this:
Simply check the box that says select a program from a list of installed programs, then click OK. You will then see something like this:
Select one of your text editor programs, such as the default Windows Notepad, then click OK. Note: If you do not want to use the text editor program to always be the default program to open .cfg files, uncheck the box that says always use the selected program to open this kind of file. If you have Notepad++, you can simply right click the file then select edit with Notepad++ and skip having to do that. If you do not have Notepad++, you can download it here: https://notepad-plus-plus.org/
In this tutorial I will be showing you how to edit it in Notepad++, but it's basically the same as using other text editors, such as Notepad.
Step 3.
Once you have the file open you will see something like this:
Look for the part where it says <item>http://update.worldoftanks.asia/ </item> (can be found on line 23 in Notepad++), you will notice that there's a space before the </item>, remove the space so it reads as . <item>http://update.worldoftanks.asia/</item> then click save.
Step 4.
Run the launcher again and it should now update. If it doesn't, recheck to make sure there's no space before the <item>. If there is no space, please paste your WoTLauncher.log in this thread which can be found in your World of Tanks installation directory.
If you need further help, you can contact Support here: https://asia.wargaming.net/support/ be sure to also attach your WoTLauncher.log in your ticket so they can see what's wrong and assist you in fixing it.
