title: Debug web addin for Outlook on MAC error
body: <p>I have developed a new web addin that targets all platforms including MAC (Office 365). 
  When I debug the addin on outlook for windows the command button appears on the ribbon -> the task pane opens -> and woks fine!
  (This is done with visual studio that opens a ISS server and connects to Office 365 account)
  On the Mac I have the latest version of Mac and Outlook and when I debug in visual studio the command button appears in the ribbon, if I click on it the task pane opens with the following error: </p>
  
  <p><strong>'sorry, we can't load the add-in.  please make sure you have network and/or internet connectivity'</strong></p>
  
  <p>I have no other errors,  and still the addin works fine on windows.  Also I din't use any method from the javascript api above 1.1.</p>
  
  <p>I am suspecting that I am doing something wrong in manifest, but it's validated -> That means I also imported the manifest directly in Office 365. </p>
  
  <p>Please tell me if I need to provide additional information.  I searched the web and I din't find any solutions for this. Thank you in advance.</p>
