Cannot access Strategy Web Services at https://WEB_SERVERNAME/StrategyWS/MSTRWS.asmx Web server error is: the underlying connection was closed: Could not establish the trust relationship for the SSL/TLS secure channel.

CAUSE:
The issue occurs because of the Secure Socket Layer (SSL) connection that the Web Services URL is using.  When the Client machine attempts to make a connection to the Web Services machine, the Client machine is unable to create a secure connection.
 
ACTION:
Install the appropriate SSL certificate. For more information regarding the error message, refer to the Microsoft Knowledge Base article through the following Uniform Resource Locator (URL):

For more information about why the Client machine was unable to find the certificate, contact a network or systems administrator, or someone who is familiar with the SSL certificates and connection setup.  SSL certificates may not be Strategy specific and may require additional configuration.
