Steps to Fix Error Code 2110-3127

Try these troubleshooting steps in order, as they are the most common fixes:

1. Restart Your Devices (The Power Cycle)

This is the simplest and often most effective fix.

1. Restart your modem and router:

   • Unplug both for at least 30 seconds, then plug them back in and wait for them to fully reboot.

2. Power cycle your Nintendo Switch:

   • Hold down the POWER Button on the console for three seconds. On the menu that appears, select Power Options, and then choose Restart.

2. Change the DNS Settings to Manual

If your router is having trouble assigning DNS automatically, you can manually set a public, reliable DNS server (like Google’s or Cloudflare’s).

1. From the Nintendo Switch HOME Menu, go to System Settings ($$).
2. Select Internet, then Internet Settings.
3. Select your registered network connection.
4. Select Change Settings.
5. Go to DNS Settings and change it from Automatic to Manual.
6. Set the Primary DNS to: 8.8.8.8
7. Set the Secondary DNS to: 8.8.4.4
8. Save the settings and try the connection test again.

3. Improve Signal Strength

If you are using a wireless connection, move your Nintendo Switch closer to the Wi-Fi router to ensure a stronger signal. Wireless signals can be blocked or degraded by walls, metal objects, and other electronic devices.

Try forgetting the network settings and setting up the connection fresh.

1. From the Nintendo Switch HOME Menu, go to System Settings ($$).
2. Select Internet, then Internet Settings.
3. Select your registered network.
4. Select Delete Settings.
5. Search for the network again and re-enter the password.

If the problem persists, you may need to check your router’s firewall settings or contact your Internet Service Provider (ISP).
