Nintendo Switch Error Code 2137-0240 — What It Means & How to Fix It

What Does This Error Mean?

Error 2137-0240 means your Nintendo Switch could not connect to Nintendo's online servers. Your Wi-Fi may be working, but the connection to Nintendo's services failed. This is usually a temporary server issue or a network settings problem.

Affected Models

Nintendo Switch
Nintendo Switch Lite
Nintendo Switch OLED

Common Causes

Nintendo's online servers are temporarily down or under maintenance
Your internet connection is working but cannot reach Nintendo's servers
Your router's firewall is blocking connections to Nintendo's server addresses
Your Switch's DNS settings are slow or unresponsive
High traffic on Nintendo's servers during a major game launch or sale

How to Fix It

Check Nintendo's server status. Visit nintendo.com/consumer/network/en_US/network_status.jsp on your phone. If servers are listed as down, just wait for Nintendo to resolve the issue.

Server maintenance is common on Tuesday and Wednesday evenings. Always check this first.
Restart your router and modem. Unplug both, wait 30 seconds, plug them back in, and wait 2 minutes before testing your Switch.

Most connection errors are resolved with a simple router restart.
Test your internet connection on the Switch. Go to System Settings > Internet > Test Connection. Check the results and note any failed steps.

If the test shows your connection is fine but Nintendo cannot be reached, the issue is on Nintendo's end.
Change DNS settings on your Switch. Go to System Settings > Internet > Internet Settings > select your network > Change Settings > DNS Settings > Manual. Set Primary to 8.8.8.8 and Secondary to 8.8.4.4.

Better DNS servers improve your Switch's ability to locate Nintendo's servers reliably.
If you use a router with a built-in firewall, make sure it allows outbound connections on ports used by Nintendo Switch: TCP and UDP 433, and UDP 1 to 65535.

Most home routers do not need these changes. This only applies if you have a custom or business-grade router.

When to Call a Professional

Error 2137-0240 almost never requires professional help. If Nintendo's servers are online and you still cannot connect, check your router's firewall settings. Contact your internet service provider if you suspect your connection is blocking gaming traffic.

Frequently Asked Questions

Do I need Nintendo Switch Online to play games online?

Yes. Most online multiplayer games require an active Nintendo Switch Online subscription. You can buy a monthly, 3-month, or 12-month plan at varying prices. Without a subscription, you can still connect to the internet but cannot play online multiplayer.

Why does this error happen only when launching online features, not the rest of the time?

Online game features connect to different Nintendo servers than basic eShop browsing. Those specific servers may be under load or maintenance while others are fine. Trying again in 15 to 30 minutes usually resolves it.

Can I use a VPN with my Nintendo Switch?

Not directly on the Switch — it does not have built-in VPN support. Some users set up a VPN on their router, which then routes Switch traffic through it. This is advanced and generally not necessary for normal use.
