VCF 9.0.1 deployment via VCF Installer gets stalled at 67% completion

Issue/Introduction

While trying to deploy VCF 9.0.1 stack via VCF Installer, installation gets stuck at 67% completion.

Environment

VCF Operations 9.0.1

Cause

• VCF Installer fails due to temporary loss of connectivity between the installer and SDDC Manager. Due to loss of connectivity, VCF installer couldn't accurately get the task status from SDDC Manager by polling the v1/tasks API so it fails.
• Entries found in domainmanager.log:
