Heartbeat 1.15.1122.0 Error: Standard exception: use_private_key: unsupported - no Heartbeat

Heartbeat is becoming my best friend.

Yesterday I identified a Windows Server that had no heartbeat due to expired certificates. I reinstalled the agent and all was fine.

Later the endpoint updated the heartbeat component from 1.15.835.0 to 1.15.1122.0 and since then, it does no longer appear with heartbeat on the firewall again.

I have never seen that error message - any suggestions on that? Standard exception: use_private_key: unsupported - no Heartbeat

I have not found a use_private_key in the HBT config or xml files on the client.
