B1 cloud can't register Prestation server

Hi experts,

I'm installing a B1 cloud on Hana.

My problem is that when I try to register a presentation server i get the error "SLD Agent Service not found..."

But I have installed the SLD Agent successfully on the serveur, and I can see it in the lit in the "SLD Agents" menu on the cloud control center web interface.

Any idea? is there a specific port to open form CCC to Presentation server?

Thank you for your help

PS: im using B1 Cloud 1.1 SP 3 (latest version atm)
