Ghost uses ZeroSSL certificate. Does it automatically renew every 90 days?


I notice that Ghost uses ZeroSSL. Do the certificates automatically renew every 90 days, like the ones directly issued by Let’s Encrypt?

Thank you.

I’m getting conflicting answers from the forum members.

  1. Ghost CLI is set up to renew it with a cron job:
    Ubuntu 20 LTS and Nginx

$ sudo crontab -u root -l

If you see something like this:
7 0 * * * “/etc/letsencrypt”/ --cron --home “/etc/letsencrypt” > /dev/null

It means, it’s configured for auto renew.

From a functional perspective, ZeroSSL and LetsEncrypt operate the same way - they provide you with a certificate which is valid for ~90 days

Internally, the Ghost CLI calls which in turn configures auto-renewal of certificates to run monthly. So you shouldn’t need to manually update your certificate
