I needed to add a subdomain to one of my certificates on an existing server. I tried the certbot command with “–duplicate” and also “–expand”. It kept saying it didn’t have the correct permissions to validate it. So I spun up a new server, pointed the A, AAAA, and CNAME records at the new server and re-ran the certbot command again and the ssl certificates were generated.
So what I was wondering is if there is a recommended way to just clear out letsencrypt files/data in order to regenerate the ssl certificates.
