BMR on Xenserver

Hi All

I have a problem.

i make a full backup of a xenserver vm with BMR collection activated.

My backup is successfully ending and no errors appears to collect of bmr data.

I make my SRT, i build my iso to boot on client.

when i start a client on iso , GUI is charged succcesfully but when i want launch restore operation, a popup is done : failed to retrieve any configurations from the server

 

i have copied mu original config to a new config nammed bmr and i have changed mac address of network card.

ping is ok between netbackup console ti client, appliance to client but i 'm unable to restore my machine.

Any idea please help me
