The request was aborted: Could not create SSL/TLS secure channel.

I am trying to call HttpWebRequest like this:



HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://api.paypal.com/nvp?[some parameters]");


I then read the response like this:


HttpWebResponse wr = (HttpWebResponse)request.GetResponse();


But unfortunately, I get the following error:


"The request was aborted: Could not create SSL/TLS secure channel."


Do you know what may be causing this?


Any help would be appreciated...

I think this is a security error related to the paypal certificate. They have two authentication options: certificate & signature. I am using the signature now and everything seems to be working correctly. I just don't know if that's a problem with the certificate on the asp server or if it's a paypal issue...
