Found a similar issue from some time ago.
#3388 @doggy8088 @madalinignisca

If the IP of the master node changed, how would I know? Where would I find the new IP?

Hi @ThePieMonster, you should either ensure that the VM has the same IP address across reboots (see linked issue for some steps), or simply see the current IP (by means of ifconfig on the VM) and adjust your kubeconfig accordingly.

@neoaggelos The host machine that is running MicroK8S is a physical windows server machine with a static IP.
I don't see how that would impact this however.

Ah, okay, this could probably be a different kind of issue than the one you linked. I am seeing this in the logs of k8s-dqlite:

Mar 31 18:07:44 microk8s-vm microk8s.daemon-k8s-dqlite[1776]: /snap/microk8s/6541/bin/grep: /usr/local/lib/sysctl.d/: No such file or directory

Can you try to create this directory manually? Running something along those lines on the VM should help:

sudo mkdir -p /usr/local/lib/sysctl.d/
sudo snap restart microk8s

Then, observe the logs to see if k8s-dqlite is coming up with:

sudo journalctl -u snap.microk8s.daemon-k8s-dqlite -f

I ended up switching to MiniKube as it runs in the context of Docker or Hyper-V without issue.
