Connection Problem

Hello, for a long time now, after some matches in Ultimate Team modes end, I get the message “Your connection has been lost, you are logging out” shown in the attachment, and it throws me back to the main menu as if I had quit that match, followed by a BDM warning. This has started happening constantly, especially in Gauntlet 9. I'm on the third round and can't play the match at all. Even if I quit, it doesn't count as a loss, but I can't play that round in any way. I would appreciate your help.
