Revoking LetsEncrypt Certificates
If you wish to remove a certificate from your server it can be revoked using a subcommand with Let’s Encrypt client. The command below can be used to revoke a particular certificate.
$ sudo certbot revoke --cert-path /etc/letsencrypt/live/your-domain.com/cert.pem
Note: Replace your-domain.com with the domain which certificate you wish to revoke.
The process does not give a confirmation upon completion, but if you perform it again you will get a message that the certificate has already been revoked.
