title: HTTPWebRequest Could not create SSL/TLS secure channel
body: <p><Br><br>
  I am trying to call a Web API using HttpWebRequest(Console Application).
  To upload the file, I am using the code snippet provided by @Cristian Romanescu ont this question <strong><a href="https://stackoverflow.com/questions/566462/upload-files-with-httpwebrequest-multipart-form-data">Upload files with HTTPWebrequest (multipart/form-data)</a></strong> 
  <br><br>If I set the req.ProtocolVersion as HttpVersion.Version10,I get Bad request when I try to do req.GetResponseStream().<br></p>
  
  <p>If i set the req.ProtocolVersion as HttpVersion.Version11,I get <strong>Could not create SSL/TLS secure channel.</strong>  when i try to do req.GetResponseStream().<br></p>
  
  <p>If tried to post the data using POSTMAN, but even Postman says <strong>Could not get any response".</strong></p>
  
  <p>If I try to hit the URL using IE-11 I get HTTP 404.[I know i am not posting the actual file], but Chrome displays the custom/appropriate error message.</p>
  
  <p>I tried the solutions already provided on stackoverflow, but unfortunately they do not solve my problem.</p>
  
  <p>Thankyou.</p>
