Are you getting the 2618-0516 error code on your Nintendo Switch? This error comes with the following message: “Unable to connect to the other console(s). NAT Traversal Process Has Failed.

What does 2618-0516 error mean?

Error code 2618-0516 indicates that your Nintendo Switch cannot connect to an online service or can’t establish a solid connection when playing online with other players. 

According to Nintendo, this error is typically caused by a NAT (Network Address Translation) issue, but in my experience, it can also occur if the game you’re playing has an on-going server issue. This occurred to me before when playing Animal Crossing New Horizons and when I checked, my NAT type has never changed. I could play online fine with other players on another game but Animal Crossing New Horizons kept returning this same error code.

What are the causes of Nintendo Switch error code 2618-0516?

There are a few things that can result to Nintendo Switch error code 2618-0516.

NAT Type issue.

Ideally, you should have NAT Type A on your Nintendo Switch in order to avoid getting errors and connectivity issues, especially when you play with other online players a lot. However, NAT Type B, which is the most common NAT Type for most users, is also fine. 

If the NAT Type on your console is anything else than these two (C, D, and F), then you must do some interventions to get at least NAT Type B. 

Unresponsive router.

A glitchy network equipment may lead to connectivity issues. Make sure that you reboot your router regularly to clear its memory and possible bugs that may have developed. 

Routers that are left running for a long time may become unresponsive and cause slow downs in a home network.

Outdated router firmware.

If needed, make sure to also update your router’s firmware periodically as well. Maintaining a good working software environment in your router does not only potentially fix problems, it may also help make your network more secure.

Server issues.

On the other side of this error is a possible server issue. As mentioned above, I had the unfortunate chance to encounter when 2618-0516 Animal Crossing before. I was simply messing around in my own island and did not even visit another player’s island, which would normally trigger the system to check if your NAT type is compatible. 

If your own NAT Type is either A or B but you continue to have this error code, you may be having a server issue.

Slow internet connection.

Playing online with a slow internet connection may also lead to certain connection errors. Make sure that you run a speed test to check if your download and upload speeds are fine. Do this if you are planning on playing with another player over the internet.
