Let's Encrypt 보안서버 SSL 설치 후 2개월 지나니 갱신하라는 안내 메일이 왔다

Let's Encrypt certificate expiration notice for domain "*.wonjustory.com"

이런 제목의 메일이 왔다.

Hello,

Your certificate (or certificates) for the names listed below will expire in 19 days (on 25 Dec 18 05:13 +0000). Please make sure to renew your certificate before then, or visitors to your website 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://letsencrypt.org/docs/integration-guide/ for details.

메일 내용은 인증서 생성 후 2개월(60일)이 지났으니 갱신하라는 것이다. 3개월 마다 자동갱신 되도록 crontab을 실행했지만 이렇게 메일이 오니 잊어버리는 일은 없을 거 같다.
