title: Peer certificate cannot be authenticated with given CA certificates
body: <p>I am developing a Bot application with the Azure Bot Framework and registered the bot on Azure and enabled direct line channel.</p>
  
  <p>I have tested my application in Visual Studios (IIS Express) with Conveyor by keyoti and it works fine.</p>
  
  <p>Now I need to try to run in a docker container, so I can't use conveyor so I tried a ngrok tunnel service, but when I try to run the application, I am getting an error </p>
  
  <p><code>System.Net.Http.CurlException: Peer certificate cannot be authenticated with given CA certificates</code></p>
  
  <p>The exception is raised on turnContext.SendActivityAsync.</p>
  
  <p>NB: When I load fiddler on my machine, everything works fine, so I am not sure what the issue is.</p>
  
  <p>Please let me know if there is any setting I need to do to get this working.</p>
  
  <p>Any advice or help will be appreciated.?</p>
