Aspose.Html.HTMLDocument not working for some URLs

Hello:
I am testing Aspose.Html package for the purpose of purchasing the paid version.
i have done the following:

  1. Create a .NET core application with Visual Studio 2019 version 16.4.2; the project is targeting .NET core 3.1
  2. I install Aspose Nuget package:
    Install-Package Aspose.Html -Version 19.12.0
  3. I have the following C# code, which works:
using Aspose;
using System;

namespace BetfairSportsBook1
{
    class Program
    {
        static void Main()
        {
            String InputHtml = "https://www.google.com/";
            // Load HTML file using Url instance
            Aspose.Html.HTMLDocument document = new Aspose.Html.HTMLDocument(new Aspose.Html.Url(InputHtml));
            // Print inner HTML of file to console
            Console.WriteLine(document.Body.InnerHTML);
        }
    }
}

But I tested with other 2 URLs, but none of them is working:

String InputHtml = "https://www.betfair.com/";
String InputHtml = "https://www.betfair.es/";

All the URLs working well in any browser from my laptop PC running Windows 10 Version 1909.
Any suggestions?
