The problem of archiving always drops the line

My account had corrupted the archive before and I restarted it. Now I keep getting disconnected, the disconnect time is fixed, it’s always at the beginning of the game or at the end of each game. I switched to another account to play the game and everything is fine, no disconnections. I suspect there is something wrong with the archive.I’m not the only one around who has this problem, it’s affecting the game experience too much. I’m considering changing my account, but I’ll lose my game progress and it’s annoying.
