Web References and Visual Studio 2013 Express

I am having an issue adding a web reference to my project.

I am using visual studio 2013 express.

I go to Service References-->Add Service Reference --> Advanced-->Add Web Reference.

When I put in the URL to the .asmx, it finds the web services at the URL.  However, when I click on Add Reference, I get a message that states unable to download files from http://...asmx?wsdl.  Do you want to skip these files and continue?

1.  The error says it can download from http://, when the URL i entered was https://...

I've tried adding web reference from a web service sitting on http and it works fine.
