The user’s Sony Entertainment Network account may be incorrect or does not exist. Solution: Check that the spelling of the user’s Online ID is correct, taking care to note whether letters are upper case or lower case and ensuring that symbols such as underscores and hyphens are inputted correctly. If the Online ID is incorrect, re-enter it correctly. If the Online ID was entered correctly, attempt to connect to PlayStation Network again later.
