Don't know whether this has been posted on here but I've started a new thread so even if it has this thread will come up on Searches to help other PSN users out.
Fault - Cannot sign into PSN & get Error code - NW31456-9 or NW31456-8 or some other codes.
Fix - On your PS4 go into Network settings & set up your Internet connection Manually, Click through all the settings on Auto except the MUT settings.
Change your MUT settings from 1500 to 1473 then click through the rest, Save & Exit.
Now this fix has worked for me the last couple of days & if I go back in & change the MUT settings back to 1500 I cannot sign in again so I personally have my MUT settings at 1473.
I have no problem playing GTA5 or Fifa15 online, Joining my mates server invites working etc etc etc
With any normal fix/bodge there is a disclaimer & here is mine.
Take this fix & make your own minds up whether to try it or not, Whatever happens is Your responsibility & Nowt to do with me.
I can say as a MOH I am running these settings myself right this minute without any issues so far but it's up to You to decide whether to try them or use them.
Finally, I really hope this gets some users online as it did me.
