If the PC boots normally but remains in GGLeap's orange **Starting** status, clear the browser cache and restart the browser. If the issue persists, try another browser or device. A network or server hiccup can cause the status to remain incorrect; using another device or a VPN may work around the issue temporarily.

If only one PC cannot connect to GGLeap, test it in place of a working station and swap its network cable. If the issue follows the PC, remove the machine from the GGLeap web admin first, then remove GGLeap locally and reinstall it using the latest installer. GGLeap cannot purge the machine from the backend on request.

If the PC boots to **offline machine** mode, it is not receiving a connection. Check the LAN cable and the DNS configuration. If you cannot access the PC to change these settings, use **Ctrl + Alt + Del** and select **Sign Out**, then hold **Shift** while selecting **Restart**. Go to **Troubleshoot → Advanced → Command Prompt**, run `C:\ggLeap`, then run `del clientinterface.exe` (try `D:` instead if the file is not found), type `exit`, and let the PC restart.
