I received this email - below - but my certificate is not expiring today. Can someone confirm this is just a spam or a routine email?
Thanks
Your certificate (or certificates) for the names listed below will expire in 1 days (on 28 Feb 22 06:11 +0000). Please make sure to renew your certificate before then, or visitors to your web site will encounter errors.
We recommend renewing certificates automatically when they have a third of their total lifetime left. For Let's Encrypt's current 90-day certificates, that means renewing 30 days before expiration. See https://urlsand.esvalabs.com/?u=https%3A%2F%2Fletsencrypt.org%2Fdocs%2Fintegration-guide%2F&e=c8f0cf02&h=3e4a1635&f=y&p=y for details.
