PS5 DNS Error: How To Fix PS5 Error Code NW-102308-4 'DNS Server Cannot Be Used'

While the PS5 is undoubtedly a fantastic console, it does still suffer from its fair share of error codes like the PS5 DNS error, which can rear its ugly head as error code NW-102308-4.

While this doesn't exactly trip off the tongue, if you are unlucky enough to be struck by it, it will certainly hamper that long-awaited gaming session. You deserve that gaming session. So let's explain what's going on with this error, and get your life back on track.

Below, you'll find everything you need to know about the PS5 DNS error and how to fix the error code and play Sony games again.

What Is Error Code NW-102308-4 On PS5?

While the official designation doesn't mean much (we like to think that NW stands for Not Working) the outcome very much does. If you get error code NW-102308-4, you'll receive the accompanying message:

A communication error has occured.
An error has occurred while connecting to the PlayStation Network.

In summary, there is an issue between your console and the PlayStation network, potentially caused by a DNS (Domain Name System) issue. DNS is essential to the proper functioning of the internet, as it's what translates the host addresses such as into an IP address - the series of numbers that computers use to find the right website.

So when that isn't working, your PS5 won't talk to the network properly. So if that's the problem, what can we do about it? Let's see.

How To Fix PS5 Error Code NW-102308-4

Thankfully, Sony has already recognised this as a problem, so have a comprehensive list of suggestions to help overcome it:

  • Check the PSN status page to see if there are any server failures or maintenance going on.
  • Restart your PlayStation 5, and connect to the Internet using a wired connection if possible. Configure the network settings again.
  • If using a wireless connection, review the installation location, for example by bringing your PS5 closer to your router or removing anything interrupting the connection between the devices.
  • Turn off your router and modem and wait at least 5 minutes, then restart it.
  • Update the firmware of your router. (For details on how to update, please contact the router vendor.)
  • If possible, try opening these ports. TCP: 80, 443, 3478, 3479, 3480 and UDP: 3478, 3479, 49152 to 65535.For help with port opening and router settings, please contact your ISP (Internet service provider).
  • In the network settings, set up a static IP address manually to improve it.
  • It could be improved by changing DNS settings temporarily. Go to DNS settings in the Network Settings, and configure your network settings with the number of a public DNS that is free and open to the public by companies or organisations. If the above does not solve the problem, the line is likely to be temporarily busy. Please leave it for a while and try again later.


In summary, try restarting your console and your router. Try to reduce the number of devices and apps fighting over your bandwidth. Move your PS5 closer to your router, or try a wired connection instead.

If none of this works, move on to the more technical solutions, such as updating firmware or changing open ports. But Sony seems pretty confident that even if none of these options works, the fault will resolve itself eventually.
