Exchange 2010 EMC/Powershell error connecting to DAG member

Exchange 2010 SP3 with UR14 on all members.

Pre-question question: should the EMC and EMS be able to connect to Exchange servers with only the Mailbox role installed?

2 servers with HT/CAS roles (not a CAS array)
2 servers with mailbox role only - DAG, failover cluster

The Exchange Management Console will connect to the HT/CAS servers from the console on any of the Exchange servers.

None of the servers will connect to the 2 servers with only the Mailbox role.  The error in the EMC is:

The attempt to connect to http://<fqdn-of-mbx-server>/PowerShell using "Kerberos" authentication failed: Conecting to the remote server <fqdn-of-mbx-server> failed with the following error message: The client cannot connect to the destination specified in the request.  Verify that the service on the destination is running and accepting requests.  Consult the logs and documentation for the WS-Management service running on the destination, most commonly IIS or WinRM.

I've checked dozens of similar messages and solutions, ranging from time sync issues to incorrect settings on the PowerShell virtual directory on the affected servers.

Sorry for the delay.

I found the answer - too obvious:  "unsupported OS"

The server was originally provisioned with 2012r2.
Oddly, it had been working for well over a year aside from the EMC issue.  The EMC issue was only discovered in trying to resolve an issue on the CAS.

Thanks.

I didn't run the troubleshooting tool - I assume it would check OS version and likely would have told me it was unsupported.
