  • ESXi host Host might have multiple IPs, while some of them are not reachable by the Transporter.

Make sure that:

  • Source and target ESXi hosts can be pinged from the appropriate Transporter (using both DNS name and IP).
  • If ping fails, edit the HOSTS file on the Transporter machine and specify the proper DNS resolution rules.
