Unable to connect at the moment of successful matching

[970319835]

I have built it multiple times, the latest version. The backend and front-end are running normally, and the game whitelist has also been added to the backend. At this point, I matched my friend and after a while, they disconnected. On the Mario racing car, it prompted error code 86420. I think this is a match, but I cannot connect. I have checked a lot of information but cannot solve it. Can you please give me some guidance on where the problem is?

Hey, I'm no longer actively maintaining this repo, which incidentally suffers from compatibility issues on newer versions of debian/ubuntu. Unfortunately no one has ever made a pull request.

All I can give you is this, but I assume you've already found this page: https://wiimmfi.de/error?e=86420

I have deployed ubuntu18.04 and 20.04, and there are some strange mistakes, so I still use 16.04, just like 16.04 at present. Every time I use 16.04 to install, the front and back ends of the webpage can't be opened. When I try to start apache2, I can enter the webpage. Everything looks perfect. I go to the background controller to add the game whitelist, and then the local game makes dns changes and enters the game. Connection successful! Start matching! Oh! Error reporting, my friend and I tried for several hours, and 100% reported the error. We have never been online successfully. I use a portable hotspot to ensure that it will not be tampered with by the router dns, but I can't solve this error. I don't know what the problem is when I am at google.Usually, the server connects successfully, but the player fails to connect. I use this server to play dbzbt3, which is my favorite game. I hope to change the problem that he can't connect online at present, so I can only ask you because you are an expert in this field. In fact, I used your script two years ago. At that time, I didn't ask questions, so there were many questions, but it was also this mistake in the end. Now, two years later, I hope you can help me. Thank you for providing such a good project.
