TLS is not activated on monitored host

Hello everyone,

I upgraded my CheckMK appliance firmware to 1.5.1 today and the site to 2.1.0. I am using Agent Updater with a certificate. Since the latest update, all Windows servers (2022 and 2016) are reporting the following error to me

Version: 2.1.0, OS: windows, TLS is not activated on monitored host (see details)WARN

and the Linux servers

Version: 2.1.0, OS: linux, TLS is not activated on monitored host (see details)WARN

I’ve already tried to activate the TLS on the windows servers via the registry, but that didn’t help. Does anyone have an idea what I have to do?

Thanks and bye,

Sascha

The checkmk agent now uses TLS to talk to the monitoring server. For more details read Monitoring Windows - The new agent for Windows in detail
