How to Fix Dolphin Traversal Server Connection Error

Dolphin is an open-source emulator that helps Nintendo console users in playing online video games with enhanced features. Gamers can use it on Windows, macOS, Linux, and Android. Not just more features, but Dolphin brings better audio and video quality to the video games too. Also, the best part is that for GameCube and Wii multiplayer modes, gamers can have online sessions with their friends or other players, making the use of Dolphin quite efficient.

What is Traversal Server?

Traversal Server is a server connection for the Dolphin emulator that allows it to create a host code. As long as the host stays up, this code remains active. In case the server goes down, Dolphin cannot create a host code. The reason why the server goes down can vary from internet connection issues to server issues.

What Causes Traversal Server Error?

As discussed above, traversal server errors can occur due to varied reasons, some of which are mentioned below:

  • Outdated version of Dolphin
  • Overprotective security software
  • System cache
  • Bugs interfering with the server
  • Issues with wireless routers

Now that you have learned a lot about traversal, it is time to get into the fixes that can help you with the traversal server connection problem. So, below are the most effective solutions that have been reported to help many gamers:

Method 1: Use Latest Dolphin Version

First things first, to avoid the traversal server connection error it is important to make sure that you are using the correct and updated version of Dolphin. In many cases, it has been noticed that older versions have seen traversal error frequently while the updated ones that include fixes for NetPlay have not encountered anything of this sort.

Therefore, make sure that your version is new and also ensure that you have the same Dolphin version as your friends, as if you have different versions, it can cause compatibility issues and also de-synchronization, and eventually, traversal server connection issue.
