I did a restart and tried again, still not working.
Here are the contents of the .txt files:
While the cmd window for the Server was loading up I noticed
"Router detection/configuration starting.
If the server hangs here, set UPnP=false.
No UPnP-enabled Internet gateway found, you must configure port forwarding on your gateway manually in order to make your server accessible from the Internet."
My Router is a piece of shit, but I am absolute sure that I did all that I can to enable the ports... to be safe I also opened them in the Windows Firewall settings.
