Rust app id not working

[Cold]

so i need help because i am trying to start up a rust server. But i have a problem when i try. When i click join next to the connection info it says that  the app id is wrong and when i put the actual id in game it also does not work, and then when i click the steam update button nothing happens but that may be because i am not a admin i am just a user of the rust panel and then when I try to use the web console it cant connect to it self please help
