playit.gg

In order for people to be able to join the server I use playit.gg. It provides a tunnel from my game server to the internet as nginx proxy manager isn't really made for game servers. In order to use playit.gg you need to create an account with them and obtain a secret key from them to register your server as an agent.

playit-compose.yaml

services:
  playit:
    image: ghcr.io/playit-cloud/playit-agent:0.15
    network_mode: host
    environment:
    - SECRET_KEY=secret_key
