Lineup error

Every time I open up ultimate team and try and adjust my. it gives me a service error code and then kicks me back to the main screen where I then have to load back in to ultimate team and has been doing it to me for three maybe four days now any idea what I can do to fix it. I’ve tried deleting the game and reinstalling. I’ve even restarted my PS five I’ve done just about everything I can think of but still doesn’t work.
