Yesterday, I have played normally on Frostmourne and everything was running pretty well, but just after I tried to log in to server Frostmourne today, I am having issues.
I do have a premium so I skip the queue, the game says Connected, but does not take me to character screen. It is basically stuck on the "Connected" sign.
I can change to different servers like Blackrock and Icecrown and everything works well, I can play the game easily. The only server that I can't log in to now is Frostmourne.
I have tried to delete Cache and WTF folder, delete addons folder, etc.
