After almost 1 year without a problem, I realized that cert-manager can't produce certificates anymore.
I started seeing this error:
Error from server: conversion webhook for cert-manager.io/v1alpha2, Kind=Certificate failed: Post "https://cert-manager-webhook.cert-manager.svc:443/convert?timeout=30s": x509: certificate has expired or is not yet valid: current time 2021-12-05T01:02:15Z is after 2021-12-03T14:15:56Z
I do NOT have a problem with the existing certificates/domains. But, it can't create certs for new domains.
Also,
kubectl get cert
has the same error output.
What is the recommended solution?
