Issues with https certs locally (slrpnk.net)

I have a minipc with proxmox on it. I have tried caddy in a lxc to set up DNS challenges to my owned domain and I set the url in my router to point to the IP (for example, proxmox.DOMAIN.com could be 192.168.10.22). The hope was to have everything local within my house and nothing needs the internet to be accessed. Some services I can host in proxmox NEED https to use, which I could not get working with my own certs or ones proxmox could make, thus Caddy. However, I get proxmox with a proper cert, but i cannot get any of the other services from proxmox working. If I were doing it all manually, I would expect DNS issues with the domain, but from what I understand, Caddy by default does wildcard domains which should mean that my services should work. but they do not. Networking is new to me so perhaps I am missing something obvious. Any guidance would be appreciated.

Caddy does certs by responding to ACME challenges on port 80 and 443. You need to forward those ports from the public internet back to Caddy, have you done that?

Edit: it seems like you're doing DNS challenges. Did you compile Caddy yourself with the right plugins? Have you tested the API token work? Any Caddy logs?

Or do it like traefik can and do TLS challenge by proofing you can add TXT entries on your domain.
