So I was on earlier this morning with little issues. I wasn't connected to the server, but after two attempts I got connected and then had no issues
Come back online and I keep getting the error NW-31453-6, and the game says
"Unable to proceed. An error occured while connecting to the PlayStation Network server"
But upon testing my connection, I successfully connected to the PSN server...
I will try a different game and see if that works.
Edit:
I tried the following games
Grand Theft Auto V Online - The Rockstar game servers are unavailable right now. Please return to Grand Theft Auto V and try again later.
Call of Duty WWII - Have to update to v 1.09. Update is currently downloading without issue.
Project Cars 2 - When attempting to join an online room, I receive the error "You have been disconnected from the multiplayer session. Exiting session"
PSN Friends list - inaccessible
PSN store - Working
Test connection - always says I successfully connected to PSN... -_-

Don't blame PD guys, definitely a PSN issue.
