Hello, dialy
I think in the certificate you defined hostname is not found.

but i Initialize the Kubernetes cluster using kubeadm like this
kubeadm init --apiserver-advertise-address="{{ node_ip }}" --apiserver-cert-extra-sans="{{ node_ip }}" --pod-network-cidr={{ pod_network }} --ignore-preflight-errors=cri --node-name="{{ master_server }}"

Your docker is in running condition?

when I make # systemctl status docker.service
