How to Resolve "Disconnected: EAC: Authentication timed out" Issue

- Go to the EasyAntiCheat folder
- Run the EasyAntiCheat_Setup
- Select the Rust from the list.
- Click on the Repair Service (If there isn't the Repair button, click on the Install Easy Anti-Cheat)

Method #3
Opt into the beta release of Rust.
- Go to the Steam Library
- Right-click on the Rust

Try uninstalling and reinstall the game
