Cant host public server

when i try and start my server it says [WARN] Backend system refused server! Server might not show in the public list but i can connect to it privately and i want to know how to make it public or figure out why its not working

solved it i didnt put the auth code in the right spot

wait how do you make a sever me and my friend are trying to find out

You need a auth code make sure to put it in the config or else it won’t work and use ur public ip
