How to Fix Rust EAC Disconnected Error or Unexpected error. (Game already running)

So, this error indicates that your internet connection to EasyAntiCheat servers isn’t working properly and the game server can’t verify the game with EasyAntiCheat. Therefore, you’re getting disconnected from the server automatically.

Make sure that the EasyAntiCheat only works on the Steam client. So, it’s highly recommended to run the Rust game from the Steam client only and check whether the issue is occurring or not. This method has fixed the issue in most cases. However, if you’re still getting the same error, follow the below steps:

1. Run as Administrator

Open the Steam client > Click on Library.
Right-click on the Rust game from the left side.
Select Properties > Click on the Local Files tab.
Choose Browse Local Files > Right-click on the Rust.exe application.
Select the Open File Location > Look for the EasyAntiCheat folder and open it.
Now, right-click on the “EasyAntiCheat_setup.exe” file.
Click to mark the checkbox “Run as administrator”.
Close all files and exit Steam properly. You can also reboot your PC.
Run the Steam again and launch the Rust game.

2. Reset DNS to Default

Press Windows + R key from the keyboard and type ncpa.cpl in the Run dialog box.
Hit OK and it will open the Internet Connection settings.
Next, right-click on the Network Adapter that you’re using.
Click on the Properties > Double-click on the Internet Protocol Version 4 (TCP/IPv4).
In the General tab, click on “Obtain an IP address automatically” for the IP address.
Similarly, click on “Obtain DNS server address automatically” for the DNS addresses.
Click on the “Validate settings upon exit” checkbox to enable it.
Finally, click on OK to save changes and restart your computer.
Run the game from Steam and the problem should have gone now.
