Official Solution
This error code indicates your network is having trouble connecting with other players online. This is often caused by your network's NAT type being too restrictive for peer-to-peer connections, which are required by many games.
To resolve this, please try restarting your network hardware. If the issue persists, you may need to make configuration changes to your router, such as enabling UPnP, placing the console in the DMZ, or forwarding specific ports.
Common Symptoms
- You can use the eShop and browse online, but matchmaking in a specific game fails with error 2618-0513.
- You are unable to join a friend's lobby or have friends join yours.
- The Switch's internet connection test shows a NAT Type of C, D, or F.
- Voice chat does not work in games that support it.
Hardware Information
This is a networking configuration error, not a Nintendo Switch hardware fault. The issue lies entirely with how your home router and Internet Service Provider (ISP) handle peer-to-peer connections. Some ISPs use Carrier-Grade NAT (CGNAT), which can make it very difficult to achieve an Open NAT type without contacting them.

IntermediateStep-by-Step Solutions
Changing router settings like DMZ or Port Forwarding can have security implications. Attempt these advanced steps only if you are comfortable navigating your router's interface. Often, simply restarting your router is enough to temporarily improve the NAT type.
Restart Your Switch and Home Network
First, restart your Nintendo Switch from the Power Options menu. Then, unplug your modem and router for at least 60 seconds. Plug them back in, wait for them to fully connect, and then test your connection on the Switch again.
Check Your NAT Type
Go to System Settings > Internet > Test Connection. Wait for the test to complete. The result will display your 'NAT Type'. Type A or B is ideal. Type C, D, or F will cause this error.
Enable UPnP on Your Router
Log into your router's settings from a PC or phone. Find a setting called 'UPnP' (Universal Plug and Play) and ensure it is enabled. This allows the Switch to automatically open the necessary ports.
Place the Switch in the Router's DMZ
This is a powerful but less secure fix. In your router's settings, find the DMZ (Demilitarized Zone) page. You will need to find the IP Address of your Switch (from the Switch's Internet settings) and enter it into the DMZ field. This opens all ports to your console.
Manually Forward Ports
This is the most secure advanced solution. In your router's port forwarding section, create a rule to forward UDP ports in the range of 1 through 65535 to your Switch's IP address. This allows all necessary game data to reach your console.
