[CLIENT] Cannot acces the endgame Chat and History, Disconnect from server.

Its a bug i have been noticing for at least 4 or 5 month. When i stay too long connected my client disconnect from server. Same when I end a game, I cannot see the end game to chat with player and honor them. The bug seem to be on a ratio of 4 / 5 or my game end in a disconnect. This problem extend also to the shop who can crash also.

I already tryed to reinstall, tryed on other computer and also looked on my rooter to get all path clear. Nothing seem to work. Even when i am away from home it goes like that. My brother and his friend are experiencing this also so i dont think its a problem our side.

Please anything i might have missed ?
