What Causes Star Citizen Error Code 30005?

- Blocked access due to antivirus or firewall settings.
Now, let’s go through the steps to resolve this issue.
Step 1: Verify the Integrity of Easy Anti-Cheat
The first step is to ensure that your Easy Anti-Cheat installation is intact. Follow these steps:
- Navigate to the Easy Anti-Cheat folder in your Star Citizen directory:

- Default location:
- Locate and run the EasyAntiCheat_Setup.exe file.
- In the setup window, select Star Citizen from the dropdown menu.
- Click on Repair Service and allow the process to complete.
- Restart your computer and attempt to launch the game.
If this does not resolve the error, proceed to the next step.
