WinRM:: HTTPNegotiate::WinRMWebService Error while trying kitchen create to launch instance

Question

I was trying to launch windows-2012 instance using kitchen-ec2 and test-kitchen. I was using the below kitchen.yml file for launching instance.I observe the instance to be created but it eventually leads to this error. can any one guide me on what's wrong with my kitchen.yml or it could be related to my instance connectivity.thanks
