Important: While troubleshooting, test your connection after any changes are made to the Nintendo Switch console or network environment to determine if the change resolves your issue.
Note
Errors during the match-making process may be the result of the network environment, including the following possible causes:
- The network NAT type is not optimal for creating a peer-to-peer connection with other users.
- A large amount of latency is causing the match-making process to time-out.
- You're connected to an internet service type that is not recommended. We recommend using a high-speed, wired Internet connection such as a Cable, DSL, or Fiber Optics Internet connection.
What to do
Perform a connection test on the Nintendo Switch console, and take note of the following results:
- NAT Type
