Hi David,
I have tested ping and telnet with kubernetes clusterIP service: 10.96.0.1 , port: 443 and API server endpoint: 10.160.0.12 port: 6443, I tried configuring both in kubernetes rule under API server connection server → endpoint as shown in attached screenshot, however either of them are not working…please check the output from checkmk server pod and screenshot attached…
