Tip: Try power cycling your internet connection and resetting your PS4 before you move on to the further methods.

Disabling The Maximum Transmission Unit (MTU)

The Maximum Transmission Unit (MTU) refers to the maximum size of a data packet that can be transmitted over a network. In the context of the PS4 DNS Server Error NW-31253-4, a misconfigured MTU setting can lead to communication issues between the console and the DNS server. If the MTU value is set too high, it may result in fragmented packets, triggering the error. To resolve this, adjusting the MTU setting on the PS4 to match the network’s optimal value can often resolve the DNS Server Error.

This means that if your internet connection is weaker than usual, it can mess up your DNS server connections. I fixed the error in my PS using this method. I also found that this method helped loads of people on lowyat forum. You can turn your MTU off using the following steps:

  1. Locate Settings: Switch your PS4 on > Go to Settings from the main menu.

  5. Check the error: On the next screen, click on Do not use > Once done, save the changes, and close the settings window > Once done, you can check for any errors in the gameplay.

PSN Servers Check

PSN (PlayStation Network) server maintenance periods can lead to the PS4 DNS Server Error NW-31253-4. During maintenance, essential updates and changes are implemented on the servers, temporarily disrupting the normal functioning of the network. This can fail to establish a stable connection with the DNS server, triggering the error on the PS4. Users experiencing this issue are advised to wait until the maintenance is completed or manually configure their DNS settings to address the problem.

If you encounter Error NW-31253-4, check the PSN servers are working fine. Sometimes, the servers go under maintenance, which instigates the issue. This method was tested on my console, which aided the problem. It also helped users on PlayStation Forums. Here’s how you can implement the following procedure to eradicate the issue:

  1. Check PSN Server Ports: Appropriately connect the following PSN Servers so that anything else does not block the router and ports:
    TCP: 80, 443, 3478, 3479, 3480
    UDP: 3478, 3479

  2. Change the DNS: If you use a manual/ private DNS, go to Settings > Network > Set Up Internet Connection > Custom > Change the DNS properties to a public DNS server or set a different DNS server.

Warning: The most convenient solution will be connecting the Play Station to the modem. Another reason for the error can be some security policy or a bandwidth limiter of your ISP service in your home, so you can contact them to fix it.

Manually Fix Your DNS Settings

Incorrect DNS configuration on a Sony PlayStation can trigger the NW-31253-4 error, disrupting online gaming and content access.

To resolve the NW-31253-4 error, users should ensure accurate DNS configuration or switch to automatic settings for seamless connectivity on their PS4.

If the DNS servers are manually switched to a public server, the DNS server error shown by Play Station 4 can be corrected. I removed the error codes NW-31253-4, NW-31254-5, NW-31250-1, and NW-31246-6 with the following steps. Our team tested this method, which gave us a positive outcome.
