Infamous 0x80072EE6 error WSUS (Server 2012)

Question

Hi Folks
In a test test lab I have setup a windows 2012 R2 server (home-dc-01.pcecorp.com) and a few domain joined windows 8 clients.  The server has WSUS installed and I have configured a group policy with WSUS settings.
However the test clients report the Infamous error: 0x80072EE6 when I try to run an update.
client log snip:
2014-10-21    14:45:18:403     884    960    EP    FATAL: SLS: Failed to construct full endpoint URL, error = 0x80072EE6
I have tried setting WUServer and WUStatusServer in group policy to combinations of:
home-dc-01.pcecorp.com
http://home-dc-01.pcecorp.com
http://home-dc-01.pcecorp.com:8530      (I understand this is what I should use!)
the client is picking up the settings from group policy policy as [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate] is getting populated
I can query DNS and ping 'home-dc-01.pcecorp.com'
Date/time and zone are correctly set
I have disabled the firewall on both the server and client
Dropped a test.htm file on the server in "C:\Program Files\Update Services\WebServices\Root"and I can sucsesfully access this from a client in a browser at:  http://home-dc-01.pcecorp.com:8530/test.htm
Bindings on the 'WSUS Administraton' site are as default:
http: 8530
https: 8531
Any other ideas?
Thanks in advance

Hi,
The error code 0x80072EE6 means that the client can't recognize the protocol.
Plese post the complete windowsupdate.log here. It may give some hints.
Besides, could you try to run the WSUS Client Diagnostic Tool on the client?
