I want to tell you that I have researched a lot for this issue but without a solution. I have created the loop that will go throw my listBox1 and that contains the links, each time creating the http GET request in order to access my full source code.
The error below is often triggered when my loop hits various of urls The weirdest thing is that if I try to remove my loop and make the http GET request to that site then everything works without any issue.
“A first chance exception of type 'System.Net.WebException' occurred in System.dll System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Authentication failed because the remote party has closed the transport stream.”
I don't consider that it's the problem with my certificate as otherwise I would still get the error when I removed my loop.
Any suggestions are highly appreciated.
