Rapid Recovery 6.2.1 restore failed

Hi, I try to restore a linux machne on a VM. I boot the VM with the rapidrecovery live dvd I get an IP address and password but when I enter it on the restore tab on the GUI core console I got an error

Here is the show details

Exception chain:

  • The underlying connection was closed: The connection was closed unexpectedly.
  • Call to service method PUT failed
  • The Rapid Recovery Linux Live DVD instance cannot be reached at ''. Please, ensure that your target machine has been successfully booted from Live DVD and the specified IP address/authentication key are valid

We can ping the machine with no problem. I do not pass to "Create DVD ISO" from the GUI, I take the DVD directly on the support site. Can it be the problem?
