I tried it out yesterday. All I wanted to do was add names to my services. I managed to get Homarr to show up when I go to server.local but couldn’t then get Overseerr to show when I go to overseerr.server.local or server.local/overseerr
So after an hour or so of fiddling I gave up.
I use Tailscale so I just don’t need to have everything sent to my domain, but I’m struggling just keeping it all on the local network.
