When attempting to update the license on an Edge SWG (ProxySG) application running on an Integrated Secure Gateway (ISG), the error "another license download already in progress" may occur. This indicates that a previous license update process has hung and is preventing new download attempts:
The error message License update failed for license ID XXXXXXXXXX Error: -14206-another license download already in progress is displayed when initiating a license update via the CLI or UI.
License updates fail consistently despite active network connectivity.
Platform: Integrated Secure Gateway (ISG)
Application: Edge SWG (ProxySG)
A hung background process is preventing the license download. Follow these sequential steps to resolve the issue:
Verify Network Allowances: Ensure that your network security devices are not blocking the appliance from communicating with the licensing servers.
Whitelist Required URLs: Verify that all required licensing URLs and ports are allowed through your firewall and gateway. Specifically, ensure the appliance can reach device-services.es.bluecoat.com and bto-services.es.bluecoat.com.
Reboot the ISG: If network configurations are correct and the issue persists, the licensing process requires a hard reset. Schedule a maintenance window to reboot the SSP ISG system. A full system reboot will clear the stalled background process and release the lock on the license download queue.
