pp_response = (SetExpressCheckoutResponseType)caller.Call("SetExpressCheckout", pp_request);

Never, ever, accept code from a insecure website to handle anything to do with real money.
You do not know who is giving you the code, you do not know what it does, you do not know that it places the monies correctly into the appropriate account, without passing the details to any third parties.

Only get such code from Paypal themselves - the scope for fraud otherwise is far too large. And remember, you personally could be liable for any monies lost if your action is seen to be negligent - which getting your code from a public forum would most certainly be!

I was also facing the same problem. Later i come to know after lots of analysis that Paypal has upgraded its TLS protocols(as per Link ).

Now for .NET 4.5 and higher, we can set the http webrequest protocol to TLS 1.2 to higher but .NET 4 or lower doesn't support TLS above TLS1. Hence the fix is directly assign the port for TLS1.2

C#

ServicePointManager.Expect100Continue = true;
              ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;
              ServicePointManager.DefaultConnectionLimit = 9999;

              OAuthTokenCredential tokenCredential = new OAuthTokenCredential(ConfigurationManager.AppSettings["PayPalClientID"].ToString(), ConfigurationManager.AppSettings["PayPalClientSecret"].ToString());
              string accessToken = tokenCredential.GetAccessToken();

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