Search for CA cert in GitHub and the forum - that definitely look like some of the quirks people ran into (including myself). I would link them but I’m a bit short on time at the moment so I figured at this comment could help you…

The error is unrelated and a dummy for the functioning of Rancher, it will be looked at to remove it in a future release.

If you can post the output of docker logs kubelet on host 172.23.3.73 we can see why kubelet can’t start.
