you’d need to look at the pod logs to see why etcd and the apiserver aren’t working. if there are no pod logs, then check the containerd and kubelet logs

I did, and it seems that the pod was attempting to check in to the control plane over ipv6 (which I have not configured), so I forced it to ipv4 by editing the startup script, and it's off to the races. No idea where the ipv6 config came from, or if it will return.

you probably have an ipv6 address in the node address list. You can look at

kubectl get node -o yaml
