kubectl minikube renew certificate

Question

I'm using kubectl to access the api server on my minikube cluster on ubuntu but when try to use kubectl command I got an error certificate expired:

/home/ayoub# kubectl get pods
Unable to connect to the server: x509: certificate has expired or is not yet valid: current time 2021-08-30T14:39:50+01:00 is before 2021-08-30T14:20:10Z

Here's my kubectl config:

/home/ayoub# kubectl config view
apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: DATA+OMITTED
    server: https://127.0.0.1:16443
  name: microk8s-cluster
contexts:
- context:
    cluster: microk8s-cluster
    user: admin
  name: microk8s
current-context: microk8s
kind: Config
preferences: {}
users:
- name: admin
  user:
    token: REDACTED
root@ayoub-Lenovo-ideapad-720S-13IKB:/home/ayoub#    /home/ayoub# kubectl config view
apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: DATA+OMITTED
    server: https://127.0.0.1:16443
  name: microk8s-cluster

How I can renew this certificate?

minikube delete - deletes the local Kubernetes cluster - worked for me
