Expanding certificates?

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: www.koalatyworks.com

I ran this command:

It produced this output:

My web server is (include version): nginx version 1.16

The operating system my web server runs on is (include version): Ubuntu Server LTS 18.04

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): 0.31.0

I’ve apparently neglected to include my mailserver’s name in my certificate. Is there a way to expand my certificate or do I need to start over?

Hi @DaddyWarlock

please check

-d and --cert-name in combination should work.

Generally, you will want to list all of the names that should be included in the new certificate. Then the certificate will be reissued for those names and replace the old certificate.
