VMware Cloud Director Availability 4.x
This issue occurs when the Cloud Director Availability appliance is unable to resolve the Platform Services Controller address specified in the Lookup Service section of the wizard.
To resolve this issue, ensure that each Cloud Director Availability appliance can resolve the address of their local Platform Services Controller.
Note: If you plan to use FQDNs for components in a Cloud Director Availability installation, you must verify that the FQDN of each component is resolvable by a DNS server and that reverse lookup is implemented using PTR records.
