Nintendo Switch Error Code 2155-8007 — What It Means & How to Fix It

What Does This Error Mean?

The 2155-8007 error means your Nintendo Switch cannot connect to Nintendo's online servers. This affects online gameplay, the eShop, and other features that require a server connection. The problem is usually a temporary server issue or a network problem on your end.

Affected Models

Nintendo Switch
Nintendo Switch OLED
Nintendo Switch Lite

Common Causes

Nintendo's servers are temporarily down for maintenance or experiencing an outage
Your internet connection is working but is too slow or unstable to maintain a server connection
Your router's DNS settings are not resolving Nintendo's server addresses correctly
A firewall or network security setting is blocking traffic to Nintendo's servers
Your Switch's network configuration has become corrupted or outdated

How to Fix It

Check if Nintendo's servers are having issues. Search for 'Nintendo network status' on your phone or visit Nintendo's official status page.

If Nintendo's servers are down, the only fix is to wait for them to come back online.
Restart your Switch and your router. Turn off the Switch completely, then unplug your router for 60 seconds. Plug the router back in, wait for it to fully restart, then turn on the Switch.

This clears temporary network issues on both your Switch and your router.
Try changing your DNS settings. Go to System Settings > Internet > Internet Settings, select your network, choose Change Settings, set DNS to Manual. Enter 8.8.8.8 for Primary and 8.8.4.4 for Secondary.

Custom DNS settings can bypass issues with your internet provider's DNS servers.
Test your internet connection. Go to System Settings > Internet > Test Connection. Make sure the test completes successfully and check your NAT type.

If the test fails, fix your internet connection first. If NAT type is D, you may need to adjust router settings.
If possible, move closer to your router or use a wired connection with a USB Ethernet adapter. The Switch supports wired connections through the dock's USB port.

A stronger or wired connection eliminates Wi-Fi signal problems as a possible cause.

When to Call a Professional

This is a network or server issue, not a hardware problem with your Switch. If your internet works fine on all other devices, contact your internet provider for help with router settings. You can also contact Nintendo Support at support.nintendo.com if the issue persists.

Frequently Asked Questions

Can I still play games offline while this error is happening?

Yes. Any game that does not require an online connection will work normally. Single-player games, downloaded games, and physical game cards all work offline. Only online multiplayer, the eShop, and cloud saves are affected.

Does the Nintendo Switch support wired internet?

Yes, but you need a USB Ethernet adapter. Plug the adapter into the USB port on the Switch dock and connect an Ethernet cable from your router. Wired connections are more stable than Wi-Fi and can solve many connection errors.

How often do Nintendo's servers go down?

Major outages are rare, but scheduled maintenance happens periodically. Nintendo usually announces maintenance windows in advance on their website and social media. Unscheduled outages during peak hours or major game launches can happen but are usually resolved within a few hours.
