Nintendo Switch Error Code 2110-2003 — What It Means & How to Fix It

What Does This Error Mean?

The 2110-2003 error means your Nintendo Switch is having trouble with DNS resolution. DNS is the system that converts website names into addresses your console can connect to. When DNS fails, your Switch cannot reach the internet even if your Wi-Fi connection itself is working.

Affected Models

Nintendo Switch
Nintendo Switch OLED
Nintendo Switch Lite

Common Causes

Your router's DNS settings are not working properly or are responding too slowly
Your internet service provider's DNS servers are experiencing an outage
The Switch's network settings have become misconfigured
A firewall or parental control on your router is blocking DNS requests from the Switch
The Wi-Fi signal is too weak, causing DNS requests to time out

How to Fix It

Restart your Switch and your router. Turn off the Switch completely (hold power for 3 seconds, then Turn Off). Unplug your router for 60 seconds, then plug it back in.

Wait for the router to fully restart before turning the Switch back on. This clears temporary network issues.
Change your DNS settings to Google DNS. Go to System Settings > Internet > Internet Settings, select your network, choose Change Settings, and set DNS to Manual. Set Primary DNS to 8.8.8.8 and Secondary DNS to 8.8.4.4.

Google's DNS servers are fast and reliable. This bypasses any problems with your internet provider's DNS.
If Google DNS does not work, try Cloudflare DNS instead. Set Primary DNS to 1.1.1.1 and Secondary DNS to 1.0.0.1.

Cloudflare DNS is another reliable option. Some internet providers work better with one service than the other.
Move your Switch closer to your router to improve the Wi-Fi signal. Walls, floors, and electronic devices can weaken the signal.

A weak signal causes DNS requests to time out. Being closer to the router ensures a stronger, more stable connection.
Delete your saved Wi-Fi network and reconnect. Go to System Settings > Internet > Internet Settings, select your network, and choose Delete Settings. Then reconnect and enter your password again.

This forces the Switch to create a fresh network connection with new settings.

When to Call a Professional

If changing DNS settings does not fix the issue, contact your internet service provider. They can check if their DNS servers are having problems or if your connection has other issues. This is not a hardware problem with your Switch.

Frequently Asked Questions

What is DNS and why does it matter?

DNS stands for Domain Name System. Think of it as the internet's phone book. When your Switch tries to connect to Nintendo's servers, DNS translates the server name into a numerical address. If DNS fails, your Switch has no way to find the server, even though your internet connection is working.

Will changing DNS settings affect my other devices?

No. Changing DNS on your Switch only affects that one device. Your phone, computer, and other devices will continue using their own DNS settings. If you want to change DNS for all devices, you would need to change it on your router.

Is it safe to use Google or Cloudflare DNS?

Yes. Google DNS (8.8.8.8) and Cloudflare DNS (1.1.1.1) are free, public DNS services used by millions of people. They are often faster and more reliable than the default DNS provided by internet providers. Nintendo's own support pages recommend trying these DNS settings as a troubleshooting step.
