'MicroK8S pods have no connectivity

No pods in newly created MicroK8S cluster on my Ubuntu have any connectivity, including coredns:

  $ k logs -f coredns-64c6478b6c-4pdnj -n kube-system
...
E0429 07:44:07.522557 1 reflector.go:127] pkg/mod/k8s.io/[email protected]/tools/cache/reflector.go:156:
Failed to watch *v1.Endpoints: failed to list *v1.Endpoints:
Get "https://10.152.183.1:443/api/v1/endpoints?limit=500&resourceVersion=0":
dial tcp 10.152.183.1:443: i/o timeout

However:

  $ curl -k https://10.152.183.1
{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {},
  "status": "Failure",
  "message": "Unauthorized",
  "reason": "Unauthorized",
  "code": 401
}%

What am I doing wrong? Both ufw and iptables are off:

  $ systemctl is-active ufw || systemctl is-active iptables
inactive
inactive

All my other pods also appear to have no network connectivity, although connectivity on the host machine is completely fine.

We faced with the same error after force power off of the microk8s Machine. We have tried to check iptables and coredns But no results. I suppose the problem with the kube-API. Need to check API logs.
