Fix an issue with HttpWebRequest/GetResponse() in a tiny program made with C#/Visual Studio 2017

I have a very short code (just around 150 lines) in C# to download an html page using ".Net Framework 4.7.2" and "Visual Studio 2019"

The software sends an HTTP request and receives the page content from the site.

Once it receives the response it saves the file in a folder.

It works very well for different sites, like [login to view URL], [login to view URL] and many others.

I have a problem with one specific site: [login to view URL]

On this site it was working until recently, but it doesn't work anymore.

After the software sends the HTTP request "GetResponse()" (line 51) it triggers an exception:

"The SSL connection could not be established, see inner exception. Authentication failed, see inner exception."


"The remote server returned an error: (403) Forbidden."

I need somebody that can fix the issue.

You can find in the attachment ([login to view URL]) the Visual Studio project including the source code file.
