title: Error: Could not create SSL/TLS secure channel Windows 8
body: <p>After upgrading to Windows 8, I am having problems with a web service call that was previously working. I've already verified on two Windows 8.1 machines and one Windows 8 machine that the following code fails, but it works without error on Windows 7 and Windows Server 2008 R2.</p>
  
  <pre><code>var uriString = "https://secure.unitedmileageplus.com/";
  
  HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uriString);
  
  try {
      using(WebResponse response = request.GetResponse()) {
          response.Dump();
      }
  }
  catch(Exception e) {
      e.Dump();
  }
  </code></pre>
  
  <blockquote>
    <p>WebException The request was aborted: Could not create SSL/TLS secure
    channel.</p>
  </blockquote>
  
  <p>It seems to be localized to this endpoint, as I am able to successfully make SSL calls to other URLS. I've done some Wireshark sniffing already, but not knowing what to look for, it wasn't much help. Let me know if you'd like me to provide those logs as well.</p>
