I'm sure alot of you have encountered this issue.
First of all what i know:
It has something to do with your PCs specs. Some programm is interfering with the game store. Its not the Antivirus or Firewall, i tested this thoroughly.
First thing that worked for a while was disabling the "Killer Analytics Service". This comes standard with every Killer Network Card. This fixed the issue for me but only for a while: it is back.
if you encounter this issue spam-clicking on the store fixes it magically for a short time after an arbitrary amount of tries. That is part of the bugs behaviour.
There is a way to get rid of the issue, but i dont know how.
For everyone who never encountered this: no, reinstalling, unlocking ports or changing stuff with antivirus programs do not work. also no repair is helping or any kind of "safe mode". it is a very persistant issue with some PCs and i can pinpoint it to an external program which is not world of tanks.
The Wargaming Support is also clueless of how this happens and why. the only thing they can see through their WGcheck is that something is blocking the data from an unknown source. They default to antivirus but this is not the root of the problem.
It has nothing to do with WoT perse, it is some random programm that causes this issue. So in an attempt to get a comprehensive look at the issue i want to collect all things that fixed the issue for you guys. Im sure there are alot of things that can interefere here and it is hard to pinpoint them exaclty. So if you ever encountered this issue, post your solution (or what you tried that didnt work). Lets see if we can get to the bottom of this.
This is how it looks ingame:
