Hmm I thought when I add tls internal to my reverse proxy rule for local domains, it does not get letsencrypt certs. But when I leave it out of the Caddyfile rule, it gets reachable from outside of the local network. How do I use your recommondation? Using a .home.lab domain locally with a DNS name resolve for every single local subdomain (dashboard.home.lab, grafana.home.lab, etc) right now with a caddy managing the outside and the inside reverse proxy work

.lab

Why bother asking if you know it better?
