This morning my websites weren't loading because the Let's Encrypt certificates expired despite the auto-renewal I set up. It turns out I recently moved my domains from Gandi to Porkbun and certbot wasn't able to renew the certificate using the now incorrect DNS authentication plugin.

After finding a Porkbun-specific DNS plugin, I was able to update my certificate configuration and renew them.

Onwards!

Didn't you get an email alert about a month ago? I always get one when my certs haven't renewed.

@Brad Koehn I don’t remember ever receiving an email, but I may have registered my Let’s Encrypt account with an email address I don’t use anymore (my Gmail ones).

You just helped me remember that one of my certs is used by my mail server, and I have MTA-STS turned on, and if that certificate expires I could be pretty well screwed for a while. Better change my LetsEncrypt email address.
