    I changed the order of HTTP and HTTPS profile definitions. And as seen in the screenshot, both ports started to work actively. However, a new WARN appeared on the console.

    Run

    dotnet run --launch-profile https

    Both ports are valid in browser and httpreplScreenshot 2024-03-21 at 18.18.01 If you are going to do Razor app tutorial

    dotnet watch --launch-profile https

    This can work as well, but if you try to access the page in http port in browser you will be redirect to https port. I guess because http page is not encouraged in browser anymore.

    Unless you comment out this line in Program.cs

    app.UseHttpsRedirection();

    Then you can vist pages under different protocals.

    Watch dotnet run if there is https connection setting for existing project with;

    dotnet watch -lp https

    if you have profile for https, the connection automatically will open with your browser. Otherwise, create new https connection!

    If https connection exist:

    1 - Open the launchSettings.json file.

    2 - Find the section where your profiles are listed.

    3 -Change the order of the profiles so that the HTTPS profile is listed first.

    4 - Save the changes to the launchSettings.json file.
