Hello,
today i installed Collabora Online with Docker.
How does the Docker Container Communicate with my Virtual Host? I didnt undestand that.
How do i need to setup my Apache Virtual Host, the Configuration from the Tutorial did not work for me, maybe its outdated?
And yes, i did replace the Domain in the .conf file with my own and i checked this twice.
I have got the Subdomains:
cloud.example.com, where my Nextcloud already is running.
office.example.com, for Collabora like it was recommended.
Thanks in advance for any help.
Never mind, i found out, thats because of the actual TLS-SNI issue of Letsencrypt… 
Ok i got the Certificate working now for office.example.com.
I did everything like described in the manual but now when i try to open a Document, i get the following Error:
Internal Server Error
Technical Details:
Entfernte Adresse: 93.236.68.65
Anfragekennung: 1iiveBJWvUFHKKFia0d8
Does this mean the Cloud is not properly connected to Collabora? What can i check?
The Docker image and the Apache Host seems to run properly.
In the Nextcloud settings i set the Collabora server to https://office.mydomain.com
What does
grep allow=\"true\" /etc/loolwsd/loolwsd.xml | grep Regex
say? (or whereever your loolwsd.xml is)
It says Path not found, where should this file be when i followed the guide from Nextcloud for Collabora? Or do i need to install this additionally? Then i think it was not mentioned in the guide…
I used docker, so it must be somewhere in that container, but where?
