In Web API creation exercise, response won't load, claims security issue

Question

I'm running a Web API I've set up with the instructions here: https://learn.microsoft.com/en-us/training/modules/build-web-api-aspnet-core/3-exercise-create-web-api

I have not modified this app from its original state. I used dotnet run and it says the Web App is listening on http://localhost:5116 but when I try to navigate there with a browser I can't see a response. If I go to https://localhost:5116 on my browser, I get an error that says "Secure Connection Failed". I've also tried https://localhost:5116, and my console shows the following warning:

warn: Microsoft.AspNetCore.HttpsPolicy.HttpsRedirectionMiddleware[3]

Failed to determine the https port for redirect.

How can I troubleshoot and fix this issue?

Hi McKathlin,

Thank you for reaching out to Microsoft Q & A forum. 

You can right click your application in visual studio and click "Properties".

Then click "Web" tab and you can find "Project Url" input box. Change the url in this input box from original http://localhost:50997 to https://localhost:44366.

After that, you do not need to change port number manually when you start the application in visual studio. It will browse with https://localhost:44366 automatically.
