ASP.NET Core 2.2 ERR_CONNECTION_REFUSED for http

I am struggling to get an ASP.NET Core 2.2 application to listen for http requests.

When I start the application dotnet run --urls http://0.0.0.0:5000 the command returns Now listening on: https://[::]:5001

And when trying to access the url: http://localhost:5000

I get an error message in the browser stating ERR_CONNECTION_REFUSED.

Https connections do work on port 5001, but Http on port 5000 fail.

My launcSettings.json looks like this:

"commandName": "Project",
  "launchBrowser": true,
  "applicationUrl": "http://localhost:5000;https://localhost:5001",
  "environmentVariables": {
    "ASPNETCORE_ENVIRONMENT": "Development"
  }

Please help by suggesting how to enable http.

I have disabled the HttpsRedirection in the Starup.cs, but this also has no effect:

        app.UseStatusCodePages();            
        //app.UseHttpsRedirection();
        app.UseStaticFiles();
        app.UseCookiePolicy();

To fix this scenario, ensure that the Program class configures the WebHost correctly.

In the example below, two URL strings .UseUrls("https://*:5001;http://*:5000") are provided to configure the WebHost, ensuring the service accepts both https and http on the tcp ports 5001 and 5000.

e.g.

public class Program
{
    public static void Main(string[] args)
    {
        CreateWebHostBuilder(args).Build().Run();
    }

    public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
            .UseUrls("https://*:5001;http://*:5000")  
            .UseStartup<Startup>();
}
