The service name/FQDN information you provided is invalid.

Problem

During the NSX Application Platform deployment preparation, you provided a service name or FQDN information that is invalid. The system needs this information to access the TKG Cluster on Supervisor or upstream Kubernetes cluster to deploy the NSX Application Platform components on it.

Cause

The service name or FQDN is in an invalid format.

Solution

Correct the format of the service name or FQDN, and ensure that it is in a local service domain. Use a format similar to the following.
<prefix>-<namespace>.<service-name>.<local-service-domain>.com
The correct format depends on the TKG Cluster on Supervisor or upstream Kubernetes environment you are using.
