Error : Facepunch_connector_cancelled

Hey there ! I was trying to create my own Rust Buster server , but when I try to connect to my localhost (by pressing the "home icon" on the console) , it gives me the error mentioned in the title .
Anything I can do ?
Di you followed all steps as required to create a server and setit up in the way as needed? Also can you name the file you downloaded to create a server?
