Can't Sign In to EA Account on PS4 - Help! (Star Wars: Battlefront (2015))

The problem is that I played with a friend and everything was fine. Today I decided to play, I turn on ps4, I go to the btlfront and I can’t play online, but only single cards. Writes something like "for online opportunities, log into your EA account" I click "connect" there is a "connection" and then again - "You are not logged into an EA account" What is the problem? can anyone explain? Yesterday everything was fine as always and in general everything was always good and nothing like that happened. Internet connection is working, psn is working, ps + is not over, I do not know what to do, please help.
