PVE 3.0 IHM behind Apache2 proxypass

hi all,

After an upgrade from pve 2.3 to pve 3.0, the can't access to the PVE IHM through my web server which have the role of proxypass in that case. I can access by direct connection.

The symptom : Firefox 21.0 show the source code of the page and Internet Explorer just says that there is an error in the page.

I do the schema of my situation :

INTERNET ----------> APACHE PROXYPASS ------------> PVE IHM
HTTPS HTTPS


best regards
