If something is wrong with it then nobody will be able to view your server in Rust+, even if they pair with it. They will see it loading for a while before it says the server is offline. # Making it Work⤶ # Making it work⤶ The only requirement for the companion server to work is to make the `app.port` TCP port accessible over the internet. Port forward, open it, add firewall rules for it. The default port is the game port + 67, or the RCon port + 67, whichever is the bigger. If you haven't changed any ports that means it will be 28082. ⤶ # The "companion.id" File⤶ The default port is the game port + 67, or the RCon port + 67, whichever is the larger number. If you haven't changed any ports that means it will be 28082. ⤶ If you get errors about companion server registration or push notifications aren't working then make sure your server can access companion-rust.facepunch.com over the internet.⤶ ⤶ # The "companion.id" file⤶ You may have noticed a `companion.id` file in your server's save folder recently. This file represents your server's identity to Rust+ and should always be kept with your server and its backups. Here's a list of rules for this file: * Do not give it to anyone else. * Do not use someone else's file. * Do not use the same file on multiple servers. * Do not randomly delete it. Breaking any of those rules will make your server behave weirdly in Rust+, disable notification permission for all your players, and probably require all players to re-pair with your server. A brand new identity will be generated for your server if you do delete it. There's no getting it back once it's gone! A brand new identity will be generated for your server if you do delete it. There's no getting it back once it's gone!⤶ ⤶ # Disabling Rust+ on your server ⤶ ⤶ If you need to disable Rust+ on your server for whatever reason, the proper way to do so is to set `app.port` to -1 in your server command line. This is the only way to turn it off entirely. Players will be able to see that Rust+ is disabled if they open the Rust+ menu on their clients while connected to your server.
