ok, it seems that the server dont accept a dyndns connection. It works perfectly with my current real IP

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 )
