visual studio debugging - SSL Connection / Connection Reset with IISExpress

Question

I'm using the new Visual Studio 2013 with IISExpress for the first time (previously used ASP.net Development server on VS2010). I'm running into issues trying to debug my project.

This is what I see in Chrome:

Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have. Error code: ERR_SSL_PROTOCOL_ERROR

I updated my Properies -> web file so that the Project Url uses a https URL now. However, after doing that, I now get a new error when launching:

The connection to localhost was interrupted. Error code: ERR_CONNECTION_RESET

Thanks

Answer 1

I was getting ERR_CONNECTION_RESET because my Visual Studio 2013/IIS Express configured app port number was NOT in the range :44300-:44398. (I don't recall having to dismiss any warnings to get out of that range.) Changing the port number to something in this range is all I had to do to make it work.

I noticed this after reviewing the netsh http show sslcert > sslcert.txt output and something clicking with stuff I read recently about the port numbers.
