Environment

VCF 9.1

Cause

Time zone for VCSA was set different than default of UTC (e.g., EST, etc.).

Resolution

1. Update VCSA time zone to UTC instead of custom (e.g., EST).

2. Reboot SDDC Manager. You should re-gain access to VCF Installer UI where deployment failed.

3. Re-try/Resume deployment. Deployment should now progress.
