[Cloud Management Gateway ERROR]

Hello SCCM's friends,

I'm trying to install/configure CMG, i have follow lot of thread about the configuration but finally it doesn't work properly.
When i use the connection analyzer (with Azure auth), the following error appears :

 

However all seems be alright :

 

So i have checked logs and i see errors :

Here is my mmc for certificates on my SCCM Server.

SRVAPPSCCM is my SCCM Server
xxxcmg.mydomain.fr is the CNAME for my CMG.
xxxcmg.cloudapp.net is my Azure Deployment

In my Server certificate i have added CNAME : xxxcmg.mydomain.fr .
I have also register the CNAME on my Web Host control panel (xxxcmg.mydomain.fr > xxxcmg.cloudapp.net).

So what do you think about my configuration ? Do I have to add any other information in the server certificate?

The DNS seem's right :

And here my CMG Config :

 

i have installed SCCM 2010 and i have also rebuild my CMG... I'm trying to solve this issue since 1 month but i don't found the solution
