Hostname cannot be changed after initial installation of Tanzu Hub 10.3 Tile
The customer has a issue in that they configured their Domain incorrectly on initial install and changed it afterwards. This leads to a failure on the redirect to Auth after they hit https://hub.domain.com/hub from their browser (it always redirects to the original, incorrect domain).
The work around for this issue is by connecting to the Registry VM via SSH, then restarting the UAA pod:
kubectl rollout restart deploy uaa -n tanzusm
The new UAA pod may take up to 3 minutes to fully enter running state
