Qlik Web Connector Issue--An error occurred while trying to authenticate. (status code = 500, The underlying connection was closed"

[mrubinvalley2]

I have installed Qlik Web Connector and I am trying to connect to Microsoft Dynamics CRM Connector V2. 

While attempting to Authenticate I am getting the following error:

An error occurred while trying to authenticate. (status code = 500, The underlying connection was closed: An unexpected error occurred on a send., Message: The underlying connection was closed: An unexpected error occurred on a send.)

Is there a resolution.
