Check the DNS settings on your console

As we mentioned above, this error code indicates a potential issue related to the DNS being used. If this issue reappears after you restarted your console, follow the steps below to check the DNS settings on your console:

  1. From the HOME Menu of your Nintendo Switch console, select System Settings.

If its DNS settings is set to Manually, but is not required for your network, change it to Automatic. See if you can connect your console to your network after setting the DNS settings to Automatic.

If its DNS settings was set to Automatic but your console still failed to connect to the Internet, it may suggest that there is something wrong with the DNS service from your ISP. In this case, try manually entering an alternate DNS.

Normally, after you changed to a proper DNS service, the error code would disappear.
