Cause

Cosmetic issue between hostd (ESXi) and HMS (VMware vSphere Replication) services in SSL thumbprint update reporting. Issue does not impact functionality of the SSL protocol itself. 

Resolution

This issue does not have negative impact on workloads and/or cluster's functionality. Fix is scheduled to be released in the upcoming VCF 9.1 release.
