It looks like your FQDN for the VC is not resolvable.
I'm guessing this based on the following message in the logs:
Using redirect URL
You can go to the Advanced Settings VC variables to ensure these are correctly set. See the following screenshot (get to this menu from Administration > vCenter Server Settings > Advanced Settings)
If you don't have a valid FQDN, please clear that VirtualCenter.FQDN field and fill in the VirtualCenter.ManagedIP field with an explicit IP address.
If you need help, please feel free to reach out to me over direct message.
