That error just tells you that the deployment of your vCenter object was unsuccessful.
You can try to identify the reason by consulting the LOGs but it doesn't change things much, I don't think many people will embark on an attempt to recover a vCenter object whose setup has failed or even if they succeed they will trust using it. Then again, you don't say much else that's particularly useful, even just to put forward a reasonable hypothesis.
In these situations the only valid approach remains that of a redeploy, please double-check that your DNS server resolves the FQDN name of your vCenter object is directly (A) and indirect (PTR) record resolvable and that the time is consistent. Another thing that will surely seem absurd to you, after completing "stage 1" wait several minutes before proceeding with "stage 2".
