If yours and your friend’s internet connection is fine, however, the issue could be something else. A simple reboot of the game, console, or router might not fix the issue. It might have to do with your router NAT type, unfortunately. It should work fine if your router NAT type is A or B. Head into your Switch’s internet settings and do a connection test to see what NAT type you have.

Thankfully, we’re here with a fix for that, too. Follow these steps to change your NAT type:

  • Find the admin page information on the back of your router
  • Input the username and password found on the back of your router to login to the admin page of your router
  • Enable UPnP (Universal Plug and Play) either on the admin homepage or within a backlink to the ‘media’ page
  • Now UPnP is on, you should be able to set your NAT type to that of your router’s DMZ (Demilitarized Zone). Set it to open to have it on type A or B on your Switch

Hopefully, it shouldn’t come to changing your router NAT type, however. All it should be is a poor internet connection that’s causing the error message to happen.
