Trying to set up with nginx proxy manager

[Charmandrigo]

I am following up a setup to run multiple web server apps with nginx proxy manager and I want to for my drawpile server too, but I keep getting as result the following pages:

This is for ports 8080 and 27780 as mentioned on the guide, and are set up to subdomains
Using "127.0.0.1:27780:27780" and "127.0.0.1:8080:8080" didn't worked as expected so I removed the 127.0.0.1 to be able to listen. But I got the pages you see on the screenshots.
Is there something I might be missing on my setup?

My log is:

The outside connections are working how you set them up. The first image shows you the root page of the listserver, the second image is the root page of your drawpile-srv. In the log, you can see that you're successfully accessing / on there, if you accessed /api/status/ you'd presumably see a status response instead or be prompted for authentication. If you want a HTML frontend for those, you have to actually set it up separately, the listserver and drawpile-srv only provide APIs.

What isn't working is that your listserver can't connect to your drawpile-srv. I can't tell you why this doesn't work without knowing how you set it up, maybe the containers are not in a network together or blocked from each other by SELinux or something.

I followed the "Use your own web server" part, removing the nginx part.
Unless removing that part entirely removes the website that lists all the active sessions and the web admin (which I'd like to access to manage the active sessions).
Unless I shouldn't do that if I use nginx proxy manager?

[Charmandrigo]

Alright even without the custom html website my server works, but is there a headless way to admin the sessions? Since I can't seem to have access to the admin page as well, just so I can tweak some server settings or end old sessions that are still running

You can use the API as documented at https://github.com/drawpile/Drawpile/blob/main/doc/server-api.md. To a degree, you can also use drawpile-srv --gui --remote $url to use the drawpile-srv GUI to do administration, but it doesn't have all the options that the web admin UI does.
