calicp-kube-controllers can't get API Server: context deadline exceeded

I have the problem after having installed microk8s on my Ubuntu 21.10 server:

sudo snap install microk8s --channel=1.23 --classic

Checked the pods and saw that one crushed:

$ microk8s.kubectl get pods -n kube-system
calico-node-c7h46                          1/1     Running            1 (7m38s ago)   10m
calico-kube-controllers-5ddf994775-gp8cv   0/1     CrashLoopBackOff   7 (34s ago)     10m

In logs , I see that something is wrong with the API Server:

$ microk8s.kubectl logs calico-kube-controllers-5ddf994775-gp8cv  -n kube-system

Hi could you please try this.

1. Edit /etc/modules and add in there a new line: br_netfilter . This will load br_netfilter at boot time.
2. sudo microk8s stop to stop MicroK8s services
3. Edit /var/snap/microk8s/current/args/kube-proxy and remove the --proxy-mode completely.
4. sudo modprobe br_netfilter to load the br_netfilter if not already loaded.
5. sudo microk8s start to start MicroK8s services
