Fixes for the NW-31205-1  Error Code

Fix 1: Trivial Fixes

These are some of the common fixes regardless of the reasons. These fixes can really work for you if you don’t have any idea what the error is about. The fixes are listed below:

  • Sometimes all your network speed might be hogged by other devices. Disconnect all other devices or wait until they are finished and only then, connect the PS4 system. This might fix the issue for you.
  • Make sure you have a fast enough connection for the PS4. A connection speed of more than 10 Mbps is needed for the PS4 to function properly.
  • Reset your wi-fi by powering off the router and then powering it up again. If this doesn’t work then, hard reset your router by hitting the reset button on the router for around 30 seconds.
  • Contact your ISP and tell them to update the router or the router firmware if you are using a very old kind of router. Use the current standard for better performance.
  • In case of a wi-fi connection, place the PS4 and your router close together and ensure that there are no obstacles between them. The distance between the devices can drastically impact the speed and reliability of the connection. So, it is important to have a good connection.

Fix 2: Check for the router’s content filtering

Sometimes you can accidentally block a certain server from the router. You or your ISP can do it and when you do this the NW-31205-1  error is quite obvious in the PS4. The port numbers that are used by the PSN servers are given below. You have to make sure that your ISP or your router hasn’t blocked these port numbers. If they have blocked these port numbers, tell them to unblock them. The port numbers are:

  •   TCP: 80, 443, 3478, 3479, 3480
  •   UDP: 3478, 3479

Fix 3: Change the DNS settings

Often times the real reason behind this error could be a bad DNS setting. To fix the DNS setting follow the instruction below:

  • If you are using a DNS server, Go to Settings > Network > Set Up Internet Connection > Custom and change the DNS settings to automatic. This will clear your custom DNS settings and revert it back to normal.
  • But if you want to use another DNS then, go ahead. Enter the primary and secondary DNS to get the job done.

If this fix also doesn’t work and you are still facing the problem then, it could mean only one thing. The problem lies in the server-side of things. The fix for it is just patience. Wait till the server comes back on. You can go to the PSN support page to see if the servers are down or not. Most of the time the servers go to the maintenance phase and they can be out for quite some time.
