Game cannot be advertised online

Post by DutchArjo »

Right now I am trying to setup a game with a friend of mine. Our only option is OpenRA because CNCnet doesn't support MAC.
However, when I create a game I get the 'server port is not accessible from the internet'.

I created a port forwarding rule in my router to open the correct port. I enabled uPNP but still, I get the same error. What do I have to do to get a private online game online and why is it so difficult in OpenRA while in CNC you don't have to do anything to get your game online, whats the difference?

If it says the port is not available from the internet then there is still some configuration problem. Could it be the firewall on your computer? You might also need to check if your ISP allows this.

The server port is not accessible error in OpenRA usually means your router's port forwarding isn't correctly routing external traffic to your computer.

OpenRA requires peer-to-peer connections, so you have to open ports for others to connect to your computer. CnCNet uses a middleman server, so you don't need to open ports. If you have opened ports and enabled UPnP and still have the error, check again:

Is the internal IP address correct?

Is there a firewall blocking it?

Does your ISP use CGNAT (if so, port forwarding won't work)?

If necessary, you can use a VPN like ZeroTier or Hamachi to play privately with your friends.

You should always just try to use public servers. There's no need to go through the hassle of hosting yourself

Sometimes, double-checking the port number and ensuring it matches your router settings can help resolve the issue.
