Hello,
to find Gladys’s IP address, you either have to connect to the computer with a screen and know Linux, or use an IP scanning tool and be familiar with networking.
Both solutions are not optimal for someone who is just starting out.
so for me it doesn’t work because my Gladys is in Docker inside an LXC Debian container managed by Proxmox… basically not a standard install.
mDNS works well with macOS or Linux but I think it doesn’t work on Windows.
EDIT: I just realized that it’s your host that handles the mDNS announcement.
In my view Gladys should handle that directly (or via a container that announces Gladys).
