    Hi Kevin,

     

    But this issue is not with all user machines, only specific users are facing this problem. Is there a workaround from browser perspective to resolve this ??

     

    Regards,

    Sivapratap,

        Hi Kevin,

         

        I was able to recreate the issue, by click on "Block" third party cookies in Internet OPtions > Privacy > Advanced. But the strange behavior is on the user machine even though he clicks on "Accepts" still he is facing the cross domain issue. 

         

        One more thing what i observer in his machine is - when webappproxy gets triggered from his client , it throws "Access Denied" message. Any idea why this is thrown ?

         

        https://bp365-51a5b6252d2b11.sharepoint.com/sites/SDCPortal/BPSDCRequestPortal/_layouts/15/AppWebProxy.aspx?SP.CloseWindow=true

         

        the above link throws "Access Denied" message in the user machine.

      In which case it's worth checking what zone each of the site domains is in I.e. The SharePoint site and the provider hosted app.
