Describe the bug

I run a vanilla asp.net core web app by checking the checkbox for configuring HTTPS. The application doesn't run correctly.

To Reproduce

I opened VS, then I chose ASP.NET Core Web Application. The HTTPS configuration was enabled by default. After creating the app, I run it with F5 using IIS Express and the web app is not loading.
