I realized that the certificate in question has expired.
I noticed this because it is no longer possible for me to manage the permissions on the cluster with tis error:
" Internal error occurred: failed calling webhook “rancherauth.cattle.io”: Post “https://rancher-webhook.cattle-system.svc:443/v1/webhook/validation?timeout=10s”: x509: certificate has expired or is not yet valid: current time 2021-10-12T06:55:58Z is after 2021-10-06T08:21:32Z"
I try to renew all certificate with “rke cert rotate” but without success
How I can renew this certificate?
