Cannot add server as a favourite

[mooseh]

Describe the bug so i've got the server up and running and i can see the server in the rust public server list, however i cannot add the server to favourites and i cannot see the servers ping, my server doesn't block ICMP.

when I try to add the server to my favourites I get the message 'Server "my server" has no favourite endpoint! will favourite by IP and port only' and the steam Game Servers UI just says 185.103.96.88:28016 <not responding>

To Reproduce Steps to reproduce the behavior: run the server on a public IP like so

Screenshots If applicable, add screenshots to help explain your problem.

Environment (please complete the following information):

• OS: Debian 12 Bookworm
• Docker: 27.0.3

Additional context im wondering if this is a natting issue, maybe I need to make the serve run on net: host?

also if i add +server.ip 185.103.96.88 it fails to start as that IP is not binded to a network interface in docker
