Environment

VMware Cloud Foundation 3.7.x

Cause

This issue occurs if the vRSLCM VM cannot reach the external DNS server configured.

Resolution

Before initiating the vRLCM deployment, make sure that the traffic is allowed between the dedicated network created for vRealize deployment and the external DNS server.

Ensure that the vRLCM can resolve all the vRealize components FQDN and IP.
