Odd Traefik Behavior

Traefik Traefik v3 (latest)
,

A few months ago I setup traefik for local and external (with authentik middleware) access on some docker containers. Currently all services can be a accessed at XXXX.local.YYYY.com but about half of them don't work at XXXX.YYYY.com anymore, where I receive a "DNS_PROBE_FINISHED_NXDOMAIN" error. I managed to fix access one service by removing the authentik middleware label, recreating the container, restoring middleware, and recreating again, but it seems to a fluke. Below is the label template most of them use.

Did it work at the beginning? What changed? Did you upgrade Traefik version? Introduce something like PiHole or AdGuard?

Note that you could simplify your dynamic config by creating a global http-to-https in static config on entrypoint.

All of them worked when I set them up originally back in May. The only one never got working was qBittorrent but that involves a VPN network. No major updates to Traefik currently have my compose image set to traefik:v3.0. No local DNS currently, just Cloudflare CNAMEs setup.

How would I do that? I've been figuring this out as I go.
