Unable to join the Server from the Internet: Connection refused

[Waschbärmann]

Hello Ladys and Gentlemen!

Im here to ask for help with my server. I have a fresh install of the 1.20.1 - 47.2.0 server client and can join it in my home network without any problems.

But when i try it through the internet, it doesnt work. The Vanilla server works just fine but i cant make it work with the forge server.

I have checked the ports in my router and everything seems fine. I have deactivate every firewall etc. but still, no connection.

Is there anything i can do to make it work?

Thx, The Waschbärmann ( Racoonman )
