title: TFS Online VSWebHandlerException
body: <p>
  Clone to visual Studio IDE is not working, I get Microsoft.VisualStudio.VSWebHandler.VSWebHandlerException when I click the Clone  > Visual Studio IDE option.(or any other option to open in VS)!!!</p>
  
  <p>I'm logged into to both in VS2017 AND TFS Online. VS is up to date on 15.4.4. GIT is the default Source Control Plug In. any ideas very much appreciated. My expectation is that it should just work!
