Hello, when i try to login to the server from my VK account, i get this notice after loading screen
"соединение с сервером прервано" or "connection to server interrupted"
what happen ? i tried using another account with gmail adress(not VK) and it can login succesfully into the game,
any help would be appreciated

Your account has been frozen or something like that.

if that's so, why it's happen ?
how to open the char from that account ?

I have no idea, here is support where you can ask about it:
