How to fix NW-31456-9

Connection error.

The system can't connect to either PlayStation™Network or the game server.

  1. Check that PSN™ services are available.
  2. If there are no issues with PSN services, check the official website for the game you are trying to play to find out if there is any maintenance or high traffic issues.
  3. If, after checking both, you still can’t connect, there might be a short term issue that will be fixed soon. Try again later.
