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

Question

My customer has informed my of issues with their SSL and Internet Explorer. They said they get trust issues when accessing the URL.

I am accessing JSON through HTTPS. The website sits on one server and I am using the console app on my local machine. I am trying to bypass the SSL Cert, however, my code still fails.

Can I alter HttpWebRequest to fix this problem?

I get this error using this code:

    // You must change the URL to point to your Web server.         HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);         req.Method = "GET";         req.AllowAutoRedirect = true;          // allows for validation of SSL conversations         ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };           WebResponse respon = req.GetResponse();         Stream res = respon.GetResponseStream();          string ret = "";         byte[] buffer = new byte[1048];         int read = 0;         while ((read = res.Read(buffer, 0, buffer.Length)) > 0)         {             //Console.Write(Encoding.ASCII.GetString(buffer, 0, read));             ret += Encoding.ASCII.GetString(buffer, 0, read);         }         return ret; 

Answer 1

I had to enable other security protocol versions to resolve the issue:

    ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls         | SecurityProtocolType.Tls11         | SecurityProtocolType.Tls12         | SecurityProtocolType.Ssl3; 

Answer 2

I enabled logging using this code:

The log was in the bin/debug folder (I was in Debug mode for my console app). You need to add the security protocol type as SSL 3

I received an algorithm mismatch in the log. Here is my new code:

        // You must change the URL to point to your Web server.         HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);         req.Method = "GET";         ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;           // Skip validation of SSL/TLS certificate         ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };           WebResponse respon = req.GetResponse();         Stream res = respon.GetResponseStream();          string ret = "";         byte[] buffer = new byte[1048];         int read = 0;         while ((read = res.Read(buffer, 0, buffer.Length)) > 0)         {             Console.Write(Encoding.ASCII.GetString(buffer, 0, read));             ret += Encoding.ASCII.GetString(buffer, 0, read);         }         return ret;
