Environment:
Policy server : 12.6 SP1 64 bit 
proxy server : 12.6 SP1 64 bit 
OS : Windows 2012 R12 
Cause:
The Forward Syntax in the proxy rule was not set correctly 
Resolution:
Changing the value for the forward syntax from $2 to $0 in the proxy rule configuration resolved the issue. 

Further information:

$0 
Appends the entire URI string from the user request to the destination specified in the proxy rule. 
For example, if a proxy rule forwards all user requests for www.company.com to proxy.company.com$0, and a user requests for www.company.com/employees/hr/index.html, that request is forwarded to proxy.company.com/employees/hr/index.html.
