Linux: Setted up all the port-fowarding for 24454 in router and in the computer, still not working. (Forge 1.16.5)

Please read the wiki before submitting a bug report!

Bug description I've made all the port fowarding in the router and computer (using GUFW) for the mod, but in the server, for everyone, even me, it's not working, it says that "client is not connected"

Steps to reproduce the issue

1. Go to '...'
2. Click on '...'
3. Scroll down to '...'
4. See error

Expected behavior For it to work. Since I also had this problem before, but when I went to GUFW and enabled entry for all ports, it worked, but it's broken now, after starting the server up a long time later. I did the same things I did to make it work again like I did last time: Re-did the port-fowarding on router, enabled entry and exit for 24454 in computer, except that now it won't work. I'm not sure if this is a conflict issue, probably, but I don't have a single clue to how to discover it.

Important Note (not sure) I did this in a dedicated minecraft server, that is in my own house, but not in the same computer as i'm using now.
