RTTF league

I joined the RTTF League, but I get disconnected from the server immediately after the match starts. When I restart Ultimate Team, it is recorded as if I was the one who disconnected. However, there are no issues with my internet connection. I can play Rivals and RUSH normally.

This problem also occurred in previous events such as the Europa League and the South America League, and I wasn’t able to play a single match in the end.

I have contacted support multiple times through the help section, but I have not received any response, and I am at a loss.

The file is from the Europa League event.
