Nintendo Switch 2110-3127 Error
What it means
Error 2110-3127 on a Nintendo Switch is a network connection problem related to the DNS being used. The console fails to complete its connection to the internet — typically when testing or establishing a wired or wireless connection — and shows this code. Nintendo attributes it to an incorrect DNS entered in the console's settings, or an issue with your internet service provider (ISP) or DNS service, rather than a fault with the Switch hardware.
The bottom line on the 2110-3127 error
Error 2110-3127 is almost always a DNS or network problem, not a broken Switch, and the real culprit is usually a stray manual DNS setting or a flaky ISP DNS server. A quick reset may clear it for a moment, but the code returns until the DNS itself is corrected.
Start with the cheapest move: set DNS Settings back to Automatic and power-cycle your modem and router, which is free and fixes the most common cause. Only if other devices also struggle is an aging router worth the $40–$150.

Which Nintendo switchs get the 2110-3127 error
Applies to all Nintendo Switch consoles — the original Switch, Switch Lite, and Switch OLED model — since it is a network/DNS error in the system software rather than a hardware-specific fault. The same DNS troubleshooting resolves it across every model.
How to fix the Nintendo Switch 2110-3127 error
- 1Restart the console and your network hardwareHold the Switch POWER button for at least three seconds, select Power Options > Restart. Also power cycle your network: unplug the modem and router for about 30 seconds, then plug them back in and let them fully restart before reconnecting.
- 2Set DNS back to AutomaticGo to System Settings > Internet > Internet Settings, select your network, choose Change Settings, and set DNS Settings to Automatic. If a manual DNS was entered but isn't required by your network, switching it to Automatic resolves the most common cause of this error.
- 3Manually enter a public DNSIf Automatic doesn't work, set DNS Settings to Manual and enter a public DNS such as Google's: Primary 8.8.8.8 and Secondary 8.8.4.4. Save and run Test Connection. This bypasses a flaky ISP DNS server.
- 4Improve the wireless signalPlace the Switch within about 10–15 feet (3–4 metres) of the wireless router with a clear line of sight, and move metal objects or other electronic devices away from the console and router, since they can interfere with the wireless signal.
- 5Create a new connection or try again laterFor wireless, delete the saved network and create a fresh internet connection from scratch. If the problem is on your ISP's side, the connection may simply need time — wait a while and test the connection again later.
🧰 When to call a professional
If 2110-3127 continues after restarting everything, setting DNS to Automatic, trying a public DNS, and improving the signal, the issue likely sits with your router or ISP. Contact your router manufacturer about a firmware update or factory reset, or your ISP about DNS/connection problems — and reach out to Nintendo Support if you've ruled out the network.
