PS4 Code 100/Unable to Connect to PSN

Does manually changing your server(if you can get this far) have any impact?

It does not unfortunately. Both of the servers I've tried encounter similar issues.

I've had the same issues since I've started playing this game. 2021 and this is still the ONLY game i have these issues with. 

@CptPatrickDKirk @SlXX Wanted to confirm if these issues are still happening?

It is still happening. I even migrated from PS4 to PS5 and I am still regularly getting both the Code 100 and the "Cannot Connect to PlayStation Network" error messages interchangeably when trying to log in.

Yep. Still happening. PS4,PS4 pro, PS5, and multiple locations in multiple States. I've tried everything including all the quick remedies such as logging/linking on EA, reinstalling, and changing DNS. Nothing works.

@CptPatrickDKirk Is there any changes you have made to your network settings? (not console settings but settings in your internet equipment)

Also when you connect to your network, does it show any information for either NAT or UPnP? 

CM- updated to ask additional information

No changes from when I switched to PS5 if that's what you were asking. I haven't changed any network settings outside of adjusting DNS originally. 

NAT Type 2
