This error occurs when the Internet speed is unstable, resulting in packet loss or failure to download updates. You must restore connections to an acceptable data transfer.
- Restart your console and reconnect it to the internet. You need to reconfigure the network settings, both with wired and connected Wi-Fi.
- If using a wireless network, make sure the console is far enough away from the router so that nothing is blocking the signal.
- Turn off your router and restart it after 5 minutes. After that, try updating your PS5.
- If you followed the steps above and still receive an error message, the line may be temporarily busy and you should try again later.
