User story

I was testing some free games to host for my family, and I wanted to see how well they work.

Game

Unturned

Linux distro

Ubuntu 22.04

Command

command: start

Further information

I'm having trouble with the Unturned server not listening on the required ports (27015 and 27016). It’s running in a Docker container, and I’m using the default config file. I even tried hardcoding the Commands.dat file, but it still doesn’t listen on those ports.

Relevant log output
