When the program is run, ASP.NET automatically redirects it to the HTTPS port, not HTTP. If you are using the HTTP port, you have to temporarily disable HTTPS redirection. In this case, disable the line: app.UseHttpsRedirection();

To be simpler, just put this part of the code as a comment, and undo it when necessary. Like this: //app.UseHttpsRedirection();

In the launchSettings.json file, move the https property to the top of the http property. Both of them will work and http requests will be redirected to the https port (as long as you don't disable the UseHttpsRedirection() in the Program.cs file).
