title: Fiddler https error: "because they do not possess a common algorithm"
body: <p>I am trying to monitor https traffic with Fiddler, using current newest version:2.4.4.5</p>
  
  <p>I've successfully set up https, certificates and I can see the full https encrypted traffic for example browsing my bank's web site.</p>
  
  <p>...however...</p>
  
  <p>When I trying to monitor an other server I got this error message in the response window:</p>
  
  <p>"Failed to secure existing connection for 77.87.178.160. A call to SSPI failed, see inner exception. InnerException: System.ComponentModel.Win32Exception: The client and server cannot communicate, because they do not possess a common algorithm"</p>
  
  <p>For full Fiddler window see: </p>

  <p>The client is not a in this case browser, but a custom client program, which communicates with its own server.</p>
  
  <p>My question: Is this exception misleading and in reality some other error prevents the secure channel to set up? 
  ...or...
  We have still chance to monitor this https communication?</p>
  
  <p>Thx in advance</p>
