VEIN Server Won't Start - Common Fixes

Resolve startup issues with your VEIN dedicated server using these proven solutions.

Fix 1: Verify Server Files

Corrupted or missing game files are the most common cause of startup failures.

  1. In Pterodactyl panel, go to Settings
  2. Click Reinstall Server (this won't delete your saves)
  3. Wait for reinstallation to complete
  4. Start the server again

Fix 2: Check Port Availability

VEIN requires specific ports to be available. Port conflicts will prevent startup.

Default Ports:

Game Port: 7777 (UDP)

Query Port: 27015 (UDP)

RCON Port: 27016 (TCP) - if enabled

If you changed ports in your config, ensure they don't conflict with other servers.

Fix 3: Validate Configuration Files

Syntax errors in config files will crash the server on startup.

  1. Open File Manager in your panel
  2. Navigate to ServerConfig/
  3. Check ServerSettings.ini for typos
  4. Ensure no special characters in server name (stick to alphanumeric)
  5. Verify MaxPlayers is a number between 1-64

Fix 4: Clear Cache and Temp Files

Stale cache files can cause startup loops.

  1. Stop your server completely
  2. In File Manager, delete the .cache/ folder
  3. Delete any *.tmp files in the root
  4. Restart the server
