How to fix NW-31205-1

Network connection is unstable or too weak to reach the PlayStation® server.

  1. Check the connection status of the PlayStation®4 console in Settings > Network > Test Internet Connection.
  2. Try the following:
    • Other devices on your network might be using a large amount of bandwidth. Wait until they are finished.
    • Check that your router and modem supports the PS4™ console. Contact your Internet Service Provider for details.
    • Reset your local network connection by powering off your modem or router and waiting 5 minutes before turning it back on.
    • Update your router's firmware. Please contact your router manufacturer or Internet Service Provider (ISP) for assistance if required.
    • If you are using a Wi-Fi connection, place the PS4 console system and the router closer together, make sure there are no obstructions between them.
  3. The following port numbers are used to connect with the PlayStation servers using the Internet. Make sure they are not blocked by the router.
    • TCP: 80, 443, 3478, 3479, 3480
    • UDP: 3478, 3479
  4. If you have been using a specific DNS server, go to Settings > Network > Set Up Internet Connection > Custom and change the DNS settings.
  5. If you're still experiencing difficulties, please try again later as the server may be experiencing high traffic.
