I’ve tried this morning with clearly install of RC15. The problem persist. I’ve checked if the image was correctly associated with the host. I’ve the same log file for Multicast log and the client return the same error.

I have the same issue when I deploy image on multicast. The server run under newly installed Debian 8 up to date and FOG 1.3.0-RC-14. The multicast log file is in same state than @kiiile. I have try with 2 node and with only one. The client give the error : “Invalid Multicast Session” in the both case.
