Hi, I installed nakivo on a CnetOS7 Linux machine. Next I want to create the Backup of this machine. Add the transporter works, but after that: An internal error has occurred. Reason: There was an error when collecting the host info. Error: Internal error (PhysicalDiscoveryServiceException). Machine: CentOS7 8GB DDR3 RAM Two RAID1 build with Linux Softraid SSH, Management Port, Transporter Port are opened in firewall.
