A client device can wait for an intermediary device to open a licensing window before transmitting a licensing request to the intermediary device. The intermediary device transmits the licensing request to an authentication server, which responds by transmitting a message indicating approval status of the request back to the intermediary device. The client device receives, from the intermediary device, a licensing response reporting the approval status indicated by the message from the authentication server. The client device communicates with the intermediary device via one network, while the intermediary device communicates with the authentication server via a different network.
