Port Forwarding CAX30 just doesn't work...need help please.

Usually if you cannot access the game server on the LAN (without using the WAN IP), then the port forwards will not matter much. Currently that canyouseeme site will not report servers using just UDP, and they will also not detect TCP services that are not actively being used, even if the port is forwarded.

But a site that can tell you if a port is forwarded properly without a server active on it, is GRC shields up https://www.grc.com/shieldsup

Click on proceed, then type in port 7777 then click on the button that says "User specified custom port probe". if the port is forwarded but no service is detected running on it, then it will list it as closed, but if it is not forwarded, it will list it as "Stealth"  (you can confirm this by trying a port outside of the range you forwarded as well as a port in the range)

From the looks of things, I suspect that the port is forwarded fine but something on the PC is preventing it from working properly.

I am unsure of all of the causes, but I know that ARK dedicated server has some issues with the split tunnel driver of many VPN client applications (e.g., private internet access, etc.), as well as some 3rd party AV software such as malwarebytes premium (their network shield).
