The Background-transfer(Up-loader) for metro apps is not working when using https URI. The same code works with http connection but with HTTPs it keeps on failing. I get

Exception from HRESULT: 0x80072EF3

I am using the same upload sample provide at http://code.msdn.microsoft.com/windowsapps/Background-Transfer-Sample-d7833f61 .

After a little search I found out that we have to include the certificate at Package.appxmanifest. But even that is not helping.

I am at the end of my wits to resolve this issue, so any help would be GREATLY appreciated.

I believe the issue is resolved now. Its a simple DNS setting issue.

If systems are behind Proxy: 1. Go to gpedit.msc -> Under Computer Configuration -> Administrative Templates -> Network -> Network Isolation. 2. Internet Proxy Servers for apps must be enabled with "IPaddress:Port" syntax. 3. Run the command line: netsh winhttp import proxy source=ie

If systems are not behind Proxy: Please ensure that the DNS server settings in the system setting is proper. Meaning, for Preferred & Secondary DNS servers actual DNS server addresses must be provided and not the Proxy server address.
