vCenter 7.x, vCenter 8.x
A solution user certificate mismatch for the vpxd service
Before proceeding with the steps below, take both a backup and a snapshot of the vCenter Server Appliance. If the vCenter is part of a Enhanced Linked Mode (ELM) replication setup, also take a backup or offline (powered off) snapshot of all replicating vCenter ELM nodes.
To resolve this issue,
Replace the solution users certificate using the new improved certificate management tool vCert - Scripted vCenter Expired Certificate Replacement for all certificate management/replacement workflow. This tool helps to replace certificates with VMCA signed as well as custom CA signed certificates.
This fix is applicable for all solution user certificate Thumbprint mismatches
