I had that yesterday I just had to play h2h because it didn't work on any challenge
Mine did that last week, I reported it to EA, they said it was a known fault and were working on it, 2 days later I was back on. I’d raise a ticket with the support team under technical difficulties via the chat option.
Check your lineup, it doesn’t invalid lineup anymore just that unable to connect to server. I got that because I was missing a uniform
Just trying to do my daily every time i go into the challenges no matter which one i get booted out of mut and it says our servers cannot process your request? Don't know what i can try
