Fix 1: Power Cycle Your Router

It’s possible that you are having this error due to internet issues, so try power cycling your home network:

  • Wait for about 5 minutes.
  • Also, restart your Nintendo device.
  • After the wait, power on your router and connect your device to the internet.
  • Check if the error is gone.

Note: If the error persists, visit an internet speed test website to check your connection speed. If it’s unstable or slow, contact your ISP for assistance.

Fix 2: Enter An Alternate DNS For Your Wii U

If your internet is working fine but the error is still coming then try entering an alternate DNS for your Wii U internet settings as it’s very much possible that the issue is with your DNS.

  • Go to the Wii U Menu.
  • Then choose System Settings.
  • Then select the Internet icon and tap the A Button.

  • Then choose Your Network.

  • Then tap the Arrow on the right and choose DNS.

Fix 3: Test Your Network Connection

  • In case your Nintendo device is far away from the router then consider bringing them near to each other.
  • Access your router settings and make sure your router firewall is disabled.
  • If you still get the error then you should try connecting your device over a mobile hotspot connection to check if it helps.
