For the past two days, whenever I play Rivals, I keep getting this message in-game after the first half and am repeatedly thrown out of the match. I checked my WiFi, and it's perfectly fine. I also tried uninstalling and reinstalling the game on Steam, but the issue persists. I play on PC, and everything was fine until two days ago. Can someone please help?
