After the deployment of the cloud gateway appliance, when you try to link the cloud vCenter, it fails with a thumbprint error - connection timed out.
Public IP, resolvable over the internet is set for vCenter resolution but the route to the vCGA uses a VPN.
The following error is seen
" Failed to retrieve thumbprint from th host "vcenter.sddc.example.com": [Errno 110] Connection timed out"
Impact/Risks:
Unable to link HLM with the vCGA.
This error is encountered when the resolution of the cloud vCenter in the VMC console, settings tab is set to public IP resolvable over the internet whereas the VPN is configured for routing to the on-premise environment.
This is an asymmetric path and the traffic would be dropped.
