PC's migrated to Win10 not reporting with Sophos server

Hey Sophos Community.  We have a mix of Windows 7 and Windows 10 clients that report into a Windows 2016 server that has the SEC running on it.  The Windows 7 clients are reporting into the SEC server but the Windows 10 clients are not.  Both batches of clients are getting their updates and all are up to date but the Win 10 clients won't report in.

I've done the normal trouble-shooting process and verified that the ports (8192 and 8194) are not being blocked by the Win firewall by checking the netstat -a on the clients and server.  Reviewing the ReportData from a couple Win 10 pc's:

01.12.2019 13:21:15 1564 I SAUAdapter - SAU ReportStatus::FinishedUpdate: Failed to read UpdateSource value in the UpdateStatus registry key.

That error is the one common item in the log files.  The SEC shows:

12/5/2019 1:46:26 PM fffffffd This computer is not yet managed. It is protected but has not yet reported back its status.

From the log file in the RMS\3\Agent\Logs dir of a Win 10 PC that isn't reporting in:

01.12.2019 13:11:15 1564 I SAUAdapter - SAU StartingUpdate has been set
01.12.2019 13:11:15 1564 I SAUAdapter - SAU IPCListener::Wait Waiting for more messages

01.12.2019 13:11:15 1564 I SAUAdapter - SAU FinishedUpdate has been set
01.12.2019 13:11:15 1564 I SAUAdapter - SAU ReportStatus::FinishedUpdate: Failed to read UpdateSource value in the UpdateStatus registry key.
01.12.2019 13:11:15 1564 I SAUAdapter - SAU Update status information saved to C:\ProgramData\Sophos\AutoUpdate\data\status\AUAdapter.xml
01.12.2019 13:11:15 1564 I SAUAdapter - SAU IPCListener::Wait Waiting for more messages

I'm at a loss as to what is the problem(s) and how to trouble-shoot it going further.  Any assistance would be appreciated.

*Edit*

This is the entry I have in the Win FW group policy as an exception for port 8192 and 8194->

8192:TCP:localsubnet:enabled:sophos
