SSL/TLS certificate monitoring

Expiry notifications

You will be notified 15, 10, 7, 4, 3, 2, 1 days before, and on the day your SSL/TLS certificate expiring.

If you have automated certificate renewals with Certbot but keep receiving expiry notifications, make sure that a Certbot cron job (that is supposed to renew your certificate before it expires) runs successfully.

Note that if you are using Certbot’s standalone mode, you will have to restart or reload your server after obtaining a new certificate.
