Certbot renew says: Cert not yet due for renewal. Firefox says:cert expired

Certbot thinks my cert is valid until 9/9/2018. Firefox thinks it expired today.
Please help

It would help to know what your domain name is.

Certbot is unlikely to be wrong about the certificate’s expiry date.

Some things to check:

  • Try reloading your web server
  • Check that your web server is loading the certificate from /etc/letsencrypt/live/example.org/fullchain.pem, not any other location on the system.
  • openssl x509 -in /etc/letsencrypt/live/example.org/fullchain.pem -noout -subject -dates

“apachectl restart” fixed it. Thank you very much!
