Problem with playing online

[marymooex]

Hello everyone

I just try to play yuri's revenge after a while that I didn't play. 

At first I try to play online, I joined a server and after I the game start to loading, It suddenly brought me back to the screen before loading the game (where you choose team,start position etc..) with out any warning.

I checked if I can play offline the game, and its work fine. 

What can possible make that issue?
