Dissconection of servers when paused

Hi, again, It has happened some times when I'm at a match and pause the game, I'm able to make my changes of whatever It was and when I try to go back to the match, It shows a dissconection of server message and log me out, and I still strugling the same when I finish a match, so my progress doesnt get counted ...for example this Time It log me out at a semifinal match of a tournment when I was winning to get to the final for my first Time, It get me annoyed, and again...I'm pretty Shure Is not my conection. Thanks
