If the server cannot be pinged through, it indicates that problems exist in the route between the virtual gateway and intranet server. Check the cables between the virtual gateway and the intranet server. If the connections are normal, check routing configurations.
If the port is in LISTENING state, it indicates that the port of the Web service is enabled.
If the port is disabled, enable it for the Web service.

Cause one: The network connection is faulty.
