I’m slightly freaking out. I recently ran some updates on my Linux Mint server computer. Afterwards, my modules, like Porkbun, had been removed and kept giving a 400 error when trying to add-package. Without the porkbun dns module, caddy can’t pass the keys and nothing with reverse proxy from me. The porkbun git page mentions some upgrade to the DNS system a few days ago that they said was connected to this. Any ideas of what to do? Do I downgrade Caddy until they resolve? I’m not the most computer savvy so I appreciate the help.

I've never heard of Porkbun, but it doesn't sound like a caddy issue. Let's Encrypt requires being able to resolve the DNS name you're requesting a cert for, and to be able to connect to your web service and fetch a secret to prove you own the domain. If porkbun does something like punch a hole in your LAN firewall and let in http traffic, then porkbun is the problem. Not Caddy.

    This part isn't true, you can use DNS challenge and they don't need to connect to your service. I have several services on my LAN that have never been accessible from the internet that have Let's Encrypt certs.

    That sounds like the method OP is trying to use.
