Unable to log into Ultimate team

The last 2 weeks I was having problems with my game crashing each time I enter a multiplayer mode in ultimate team that requires plus, yesterday it started with not letting login a the message that appeared was “Ea sport server unavailable. But my friends was playing at the same time so that wasn’t the problem, I delete and downloaded it again and too due to that I bought the plus for myself(borrowing it from a friend in the mean time) after I bought and downloaded the game the message keeps on appearing and doesn’t let me access, I’ve lost much FutChampions game due to this types of problem, I’ve used 3 different WiFi and that’s not the problem either
