This error indicates the user is trying to pair a mobile app with their workstation and the workstation is not on authorized network.

This issue may also be experienced in scenarios where proxies are involved in routing connections and may indicate an administrative issue.
Please follow these instructions in order to resolve the issue:
1. Check that the user is on a secure network (office or VPN) try again. This will ensure the user is ready to begin pairing.
2. If the issue persists - Try to register again but proceed quickly through the pairing process. This will ensure that end user speed is not the cause of the issue.
3. If the issue persists - Guide the user to reboot workstation before trying again.
