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.
  2. In System Settings, go to Internet > Internet Settings.
    Internet Settings Nintendo Switch
  3. Select the network you’ve registered and then select Change Settings to review the DNS settings.
    Change Internet settings Nintendo Switch

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.

To enter an alternate DNS:

  1. From the HOME Menu of your console, go to System Settings > Internet > Internet Settings.
  2. Select the network you’ve registered and then select Change Settings.
  3. Select DNS Settings, then select Mannual.
  4. You can use the public DNS provided by Google. To do so, just enter 8.8.8.8 as the Primary DNS and 4.4.4.4 as the Secondary DNS.
    manually enter an alternate DNS on Nintendo Switch console
  5. Tap the Save button on the right to apply the changes.

See if you resolved this issue after using the DNS provided by Google. If the DNS provided by Google failed to fix this issue, you can also try using SmartDNS on your Nintendo Switch.

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

Power cycle your home network

If you didn’t reboot your home network for a long time, you may also try to power cycle your network devices like modem and wireless router, since a glitch with your network devices may also lead to network issues. By rebooting your network, your Internet connection may be back to normal.

Just follow the instructions below to power cycle your network devices:

  1. Unplug your modem (and your wireless router, if it’s a separate device) from power for 60 seconds.
