Checks to determine if the Windows Update Agent is unable to connect to the Essentials server due to an automatically detected proxy server.
The Windows Update Agent is unable to communicate with the Essentials server due to a proxy configuration issue.
A proxy server on the network is being automatically used by the Windows Update Agent. The proxy server is not configured to allow FQDN traffic to the Essentials server.
Add a rule or configuration to your proxy server to route traffic destined for the FQDN of the Essentials server back internally to the Essentials server.
