hi, all. great thanks for your help. I wanna know the correct operation process for renewing cert or recovery from auto certificate renew. I noticed my cluster automatically renew its cert(p.s. I don’t know why, may be the cluster is more than 365 days?), and my

kubectl

became unavailable like

error: You must be logged in to the server (Unauthorized)

. besides, I found my

nodeport

became unaccessible and one of my

master

became UnReady. I don’t know how to recovery from it and I have thought the cert renew will be a transparent process I don’t need to care about. could anyone help me? great thanks for your help!
