Can't access admin page

Installation & Configuration
1

I have collabora install in a Truenas VM running ubuntu 20.04. Truenas runs a reverse proxy with caddy.

Entering in a browser collabora/hosting/discovery in a browser will output the contents of an xml file works
Entering in a browser same domain with /hosting/capabilities works as well but
When try to access the admin console with collabora.mydomain.com/loleaflet/dist/admin/admin.html I get HTTP ERROR 400

Here is my yml file

Hi @NasKar hm I see some lool and loleaflet strings going on there. We have renamed some of those and most likely that is the culprit, let me sending documentation reference

loleaflet needed to be changed to browser and lool to cool in my caddy file. Now it all works. Hope that helps someone else.
