Hello,
I’m having the same problem… notice you haven’t got an answer yet. I hope no one thinks our question is too basic to answer… how else do you get started with this stuff?

Could you check that the file:

/var/lib/kubelet/config.yaml

Exists on the node and if it does paste it here?

any update !

sudo cat /var/lib/kubelet/config.yaml
