Try running the server.bat file instead and see if you get the same message.
When you forwarded the ports on your router, were they UDP or TCP?
When you added the ports on the firewall, were they UDP or TCP?
- With my router, I chose UDP as the type, typed in my LAN server IP and enabled "port range". The starting port as 28763 and the end port 28764 and private port 28763, saved and rebooted the router, unblocked the server.bat in my firewall, and I was good to go.
