server not showing up

so i want to set up a server for my Karting team to test on, but it doesn't show up in the server list.

any idea to what could be the problem? is this a common issue?

many thanks,

 

Have you opened up all the ports to the machine hosting the server?

 

Would you mind to post the IP and Port that the server uses?
With that we can check if the server is accesible.

 

I Will first try what Andy said tommorow.
If it doesnt work I Will post my IP and the Ports.

 

If it helps, I opened 4 ports for mine, but you can set the ports you want to open within the json file
