title: Azure Data Factory v2 - Web Activity - Post Request to HTTPS self-signed Certificate
body: <p>I have a web server which set up a self-signed certificate. </p>
  
  <p>When I use Web Activity from ADF v2 to send a post request to the HTTPS URL, I got the error message: </p>
  
  <p>"Error calling the endpoint 'https://...'. Response status code: ''. More details:Exception message: 'An error occurred while sending the request.'.No response from the endpoint. Possible causes: network connectivity, DNS failure, server certificate validation or timeout.</p>
  
  <p>Is there anyway that I can cancel the Web Activity server certificate validation or any workaround that makes the Web Activity works with Self-signed certificate? </p>
  
  <p>I have been stuck with this problem for few days so your help is greatly appreciated. Thanks very much in advance. </p>
