Web Service not working

I'm having issues integrating my web service with docuware. I published my both my rest and soap  web service using IIS. I tested it using Postman with no errors. However, when I try to start a new web service in docuware. I get an error which reads below.
         Validation failed with error: An error occured while sending the request.

             Thanks!
