F.A.Q. Client

1. Connection to server failed?
Sorry, we cannot start the game anymore: Could not connect to server. Connection to server failed.

How to fix:

• Run the game as an administrator.
• Wait 15 minutes, then log in again.
• If you still cannot connect, use a VPN.
• If the VPN does not solve the issue, send a private message to the administration. Include your account login and IP address.
• For more help, create a live support ticket on Discord with this link.
2. Failed to download [main.exe]?
This issue usually happens because Windows Defender or a third-party antivirus has quarantined or deleted the main.exe file, flagging it as a false positive due to our client protection and encryption systems.

How to fix:

Restore from Quarantine: Open your antivirus or Windows Defender history, locate the quarantined file related to your game folder, and select "Restore" or "Allow on device".
Add an Exclusion: To prevent the antivirus from deleting the file again during updates, add your entire game folder to your antivirus exclusion list (In Windows Defender: Go to Virus & threat protection settings > Exclusions > Add or remove exclusions and select your game folder).
Re-run Launcher: Once the folder is excluded, run Launcher.exe to download the fresh main.exe without interference.

If the above solution doesn't work, please create a live support ticket on Discord and we will help you out.
3. Timeout while communicating with server?
Sorry, we cannot start the game anymore: Timeout while communicating with server after 15 sec.

How to fix:

• Check if you ran the game as an administrator and have full admin rights in your Windows profile.
• Launch the game using Pingzapper or Cloudflare WARP.
• Check your internet connection stability.
• If nothing above helps, write to the administration in private messages to solve the problem.

• Scroll down to the THE ULTIMATE SOLUTION section below.
• Download and run one of the recommended Automated Driver Update tools.
• Scan your system and update the missing or outdated drivers.
• Restart your PC and launch the game. This resolves 99% of silent crashes verified by our team.
