I'm attempting to upgrade ESXi nodes in a USCM cluster using Hyperflex Connect. Under the Upgrade navigation link, I select Upgrade. Then select ESXi, drop in the upgrade image (which validates successfully) and the vcenter credentials. It starts the Validation, and fails on:
Checking vCenter configuration
ERROR: Certificate generation failed for VC login
WARNING: vSphere upgrade from (6.7.0-16316930) to (7.0.1.17325551) cannot be Rolled Back.
My vCenter has self-signed certificates.
