I have this problem and just fixed it. I tried so much stuff like changing your DNS and resetting etc and didn't want to reinstall for obvious reasons. In the end, I managed to get in by using the hotspot on my phone. For some reason, the game updates but the version for the ps4 launcher gets stuck in the old version and claims it's up to date. Connecting to my phone triggered this ps4 side update for some reason. Super frustrating, every time there is an update my PS4 gets locked out for a day whilst I try to figure it out. I doubt I'll get those 3 days play time back!
