Windows 10: Cluster Aware Updating CAU starting an hour later than scheduled

We have Cluster Aware Updating CAU setup on a monthly schedule - Running Windows Server 2016. The past couple of months we have had incidents where CAU processing did not kick off at the scheduled time, but instead started one hour late. Is this a known issue - perhaps related in some way to DST, and are there patches available that may fix the issue?

Windows 2019 Datacenter Cluster - Configuring Cluster Aware Updating

Hello, everyone.

I am trying to configure Cluster Aware Updating (CAU) on a 2-node, Windows 2019 Datacenter Cluster. Using Failover Cluster Manager, when I run the "Analyze cluster updating readiness" function, I receive a report with two errors and one warning.

The first error is "The failover cluster nodes must be enabled for remote management via WMIv2". They already are. When I run "WINRM QUICKCONFIG -q" on each node, I get no errors; in fact I get "WinRM service is already running on this machine. WinRM is
already set up for remote management on this computer."

The second error is "Windows PowerShell remoting should be enabled on each failover cluster node". It already is. When I run "Enable-PSRemoting" on each node, I get no errors;. in fact I get no messages back at all.

The one warning is "The CAU clustered role should be installed on the failover cluster to enable self-updating mode". I think this will go away once I get CAU set up and running on this cluster.

My command to add CAU to my cluster ends up being:

Add-CauClusterRole -ClusterName ES19TESTCL1 -Force -CauPluginName Microsoft.WindowsUpdatePlugin -MaxRetriesPerNode 3 -CauPluginArguments @{ 'IncludeRecommendedUpdates' = 'True' } -RequireAllNodesOnline -StartDate "8/1/2020 12:00:00 AM" -DaysOfWeek 64 -WeeksOfMonth
@(3) -VirtualComputerObjectName ES19TESTCL1CAU -EnableFirewallRules;

ES19TESTCL1CAU is a computer name I pre-staged in my Active Directory.

The results of running that PowerShell script was: "Validation failed for adding CAU cluster role." I'm guessing once I figure out and fix what's causing the validation errors, the script will work. Any suggestions are greatly appreciated. This is my first
cluster.
