How to Troubleshoot PS5 Error Code (NW-102308-4)?

To fix the error code NW-102308-4, you need to check and improve your network connection. Here are some steps you can follow to do that:

Check the PlayStation Network Status Page to see if there is any problem or maintenance going on. If there is, wait until it is resolved before trying to connect again.
Restart your PS5 and try to use a wired connection as often as possible. A wired connection is more stable and reliable than a wireless one. To use a wired connection, connect an Ethernet cable from your router or modem to your PS5, and then go to Settings > Network > Settings > Set Up Internet Connection > Use a LAN Cable.
If you are using a wireless connection, make sure there are no obstructions or interferences between your PS5 and your router or modem. You can also try moving your PS5 closer to your router or modem, or changing the wireless channel or frequency on your router or modem settings.
Turn off your router or modem, wait for five minutes, and then turn it back on again. This can help reset and refresh your network connection.
Update your router or modem firmware if applicable. Some routers or modems may have outdated or buggy firmware that can cause network issues. Check the manufacturer’s website for the latest firmware update and follow the instructions to install it.
Open the following ports on your router or modem settings. These ports are used by the PlayStation Network and some online games to communicate with the internet. To open these ports, you need to access your router or modem settings through a web browser, and then find the port forwarding or port triggering option. The ports you need to open are:
- TCP: 80, 443, 3478, 3480
- UDP: 3478, 3479, 49152~65535
Change the DNS settings on your PS5. DNS stands for Domain Name System, which translates website names into IP addresses. Sometimes, the default DNS settings on your PS5 may not work well with your network provider or region. You can try changing them to a public DNS that is free and open to the public by companies or organizations. To change the DNS settings on your PS5, go to Settings > Network > Settings > Set Up Internet Connection > Use Wi-Fi or Use a LAN Cable > Custom > IP Address Settings > Automatic > DHCP Host Name > Do Not Specify > DNS Settings > Manual. Then enter one of the following DNS servers:
- Google Public DNS: Primary DNS 8.8.8.8, Secondary DNS 8.8.4.4
- Cloudflare DNS: Primary DNS 1.1.1.1, Secondary DNS 1.0.0.1
- OpenDNS: Primary DNS 208.67.222.222, Secondary DNS 208.67.220.220
