I’m also having this issue. I spoke to EA chat who also suggested it was my issue not the server. I tried the tips he provided including rebuilding my PS4 database in safe mode and deleting the profile save game data. Also using wired connection 

was ok for 3-4 games but this morning kicked me in 2 games in a row and now lost my Eden Hazard loan that I was trying to complete objectives with! So frustrating, not sure what else to do, my internet connection is absolutely fine
