Opponent leave the match. How to fix?

Since yesterday, my ultimate team EA24 on the xboxone hasn't worked when I play Draft of Rivals. Before, it worked well.  Even before the match starts, I get an error message. I want to start the match and press "Continue" next to my lineup. Then it searches for an opponent and I get a message that my opponent has left the match. The game then freezes, and I have to restart it. I've read about this problem online several times, but there's no solution. Changing match settings, for example, doesn't work. How do I fix this?
