How to Fix It

Restart your Nintendo Switch. Hold the power button for 3 seconds and select Power Options > Restart. This is a full restart, not just waking from sleep mode.

Re-link your Nintendo Account. Go to System Settings > Users, select your profile, and choose Nintendo Account. Unlink and then re-link your account to refresh the authentication.

An expired account session can cause error 2137-4001 when the Switch tries to verify your identity.
Check for and install any pending system updates. Go to System Settings > System > System Update. Running the latest firmware ensures compatibility with games and Nintendo's servers.

An outdated system version can cause authentication and compatibility errors.
Check the game's data integrity if the error happens with a specific game. Go to System Settings > Data Management, find the game, select Software, and choose Check for Corrupt Data.

If corruption is found, delete the game and re-download it from the Nintendo eShop.
If all else fails, try a factory reset as a last resort. Go to System Settings > System > Formatting Options > Initialize Console. This erases all data on the Switch.

Back up your save data to the cloud using Nintendo Switch Online before doing a factory reset.

When to Call a Professional

If this error appears constantly after a system update and a factory reset does not help, contact Nintendo Support. In rare cases, a failed system update can require professional firmware recovery. Do not attempt to manually flash firmware unless Nintendo Support specifically instructs you to.
