Constant "Lost connection to game server"

I've been trying to play games for hours now, I play on a ps4 and ive tried EVERYTHING. Restarting my router, restarting the ps4, testing the internet and nothing works. I either cant even get past startup or ill be halfway through a game and I get kicked. I have no idea what's going on, I know someone playing on pc that has no issues so if anyone has any advice please please please help.
