Azure Hybrid Connections To Local IIS Server Not Connecting

I found myself needing to create an Azure Hybrid connection from a web application hosted on Azure to a WebAPI application hosting on a server inside a company network.

“Visual Studio debugging – SSL Connection / Connection Reset with IISExpress – Stack Overflow

Sometimes it can be a huge pain in the rear to work with SSL on local IIS or IIS Express in Visual Studio. I was trying to debug an issue with my authentication flow and just could not get my auth server to run locally.
