What those PS4 error codes mean and how to fix them
Oh technology, how you baffle us with your numbers. When the PlayStation 4 first launched, users were greeted with two error codes upon trying to connect to PlayStation Network: NW-31453-6 and E-80E80034.
Displaying error codes is not uncommon, but it certainly is frustrating. A brief message with a bunch of jumbled letters and numbers doesn't mean much to the average user. So Sony has compiled a nice little guide that outlines what each of the common error codes mean and the action you must take to fix it.

Hopefully this helps clear up any confusion you may have if one of these should appear. If an error code is missing, let us know, and we'll contact Sony to see if we can find out more.
