Online dynasty - Error "Our servers cannot process your request"

I haven’t been able to play ultimate team or even do any  challenges for about a week now. This is really frustrating. I was able to play for like 3 or 4 days when it first came out and now nothing works, same error message everytime I try and do anything. “Our server couldn’t process your request, please try again later.” I’ve tried everything if anyone knows how to help please reply!!
