Collabora Online - additional nginx config necessary?


I have just installed Nextcloud (works flawlessly) and wanted to add Collabora. Installed it via the GUI in a separate subdomain (office.mydomain.tld) which I added to the DNS with a A-entry, pointing to the same IP than mydomain.tld. Successfully registered the let’s encrypt cert via GUI as well.
The isntallation has run without errors (at least I’m not aware of any). When I call the url in the browser the standard nginx message is shown: " Welcome to nginx! If you see this page, the nginx web server is successfully installed and working. Further configuration is required."

I’m a complete noob at nginx configuration. Do I need to add something in the config file? Respectively do you need some information from one of the many nginx-config files? I guess the relevant one is in the folder office.mydomain.tld?

My YunoHost server

Hardware: VPS bought online
YunoHost version:, Standard installation
I have access to my server : Through SSH and through the webadmin
Collabora Online version: 4.0.0~ynh1, installed from the yunohost-GUI

Any help or hints is much appreciated! I looked for a solution online, nothing specific found except for a lot of issues with collabora some years ago (which might be solved by today)

I want fast help too. If someone has working instance of collabora it would nice to explain the steps.

it’s the normal comportement for collabora,it’s the default page of nginx.It’s here because you don’t have need to visit this url to use collabora so it set to the default index page .

To use collabora you just have to use the domain you set to collabora as the wopi url in the configuration of the nextcloud collabora app

also you can access the admin pannel of collabora via [your-collabora-domain]/loleaflet/dist/admin/admin.html

Stupid me… Ok, now there is ‘unauthorized wopi host’ when opening a doc in nextcloud… But this is another story, I’ll stick to another thread.
