Nintendo Switch Error Code 2155-0001 — What It Means & How to Fix It

What Does This Error Mean?

2155-0001 means your Nintendo Switch failed to connect to the Nintendo eShop. This is usually a temporary server issue or a network connectivity problem. Most cases resolve on their own within a few minutes.

Affected Models

Nintendo Switch
Nintendo Switch Lite
Nintendo Switch OLED

Common Causes

The Nintendo eShop servers are temporarily down for maintenance or experiencing an outage
Your home internet connection is unstable or experiencing packet loss
The Nintendo Switch's network cache has stale data causing connection failures
Your router's DNS settings are failing to resolve Nintendo's server addresses
The Wi-Fi signal is too weak to maintain a stable connection to Nintendo's servers

How to Fix It

Check Nintendo server status. Visit nintendo.com/en-US/consumer-service/network/system-status/ on your phone or computer. If the eShop or online services show maintenance, you need to wait.

Nintendo performs regular maintenance on the eShop. Maintenance windows are announced on the status page and usually last 1 to 4 hours.
Restart your Nintendo Switch. Hold the power button for 3 seconds and select Power Options > Restart. After the restart, try opening the eShop again.

A restart clears the Switch's network state and connection cache, which often resolves eShop connection errors.
Restart your home router. Unplug the router from power for 30 seconds, then plug it back in. Wait for all lights to stabilize before trying the eShop again.

Router restarts fix many network issues by clearing stale connection tables and renewing the IP address from your ISP.
Move closer to your Wi-Fi router. If you are far from the router, bring the Switch within a few meters and try the eShop again. Weak Wi-Fi signal commonly causes connection timeouts.

Nintendo Switch has a compact internal Wi-Fi antenna. It may be more sensitive to weak signals than phones or laptops.
Change your DNS settings. On the Switch, go to System Settings > Internet > Internet Settings. Select your connection, then Change Settings. Set DNS to Manual and enter Primary: 8.8.8.8 and Secondary: 8.8.4.4.

Google's DNS servers (8.8.8.8) are fast and reliable. Switching from your ISP's default DNS can resolve eShop connection failures caused by slow or failed DNS lookups.

When to Call a Professional

Frequently Asked Questions

Why does 2155-0001 happen only sometimes when I open the eShop?

Intermittent eShop errors are almost always caused by brief server hiccups on Nintendo's side. They are not caused by anything wrong with your Switch. If the error is rare and infrequent, simply closing and reopening the eShop usually resolves it.

Does 2155-0001 affect game downloads already in progress?

Usually not. Active downloads continue running in the background even if you cannot open the eShop storefront. You can check download progress by going to the home screen and pressing the circle icon in the top-right corner. The eShop storefront and active downloads are handled by separate processes.

Is 2155-0001 the same as other 2155- errors on Switch?

The 2155- error family on Nintendo Switch is related to online service connectivity. Different last digits indicate different types of connection failures within that category. 2155-0001 specifically relates to an eShop connection failure. Other 2155- codes may indicate different server or authentication issues.
