The SDDC Manager GUI displays an alert indicating a failure to fetch silenced health checks:

‘Failed to retrieve silenced health checks. Invalid vsan health check query id’

You may find a message similar to the following in the vmware/vcf/lcm/lcm.log file:

The UI may retain information from a previously valid query that is no longer applicable.
