Environment

VMware vCenter Server 7.0

Cause

This issue happens due to the dpxa service registration where the URL is host name.

This can be verified by checking service registrations as per KB -

URL will show VR FQDN instead of complete URL format like "http://__/__" due to which VDT treats it as malformed.

Resolution

Currently, there is no resolution.

Engineering is aware of the issue and is working on a fix.
