Collabora in NextCloud

Scale Version: ElectricEel-24.10.1
Next Cloud Version: 1.6.2 in the stable train

I’m still trying to setup collabora so me and my familiy can use it locally in next cloud, but no idea what to do anymore.

My next cloud setup is:

  • no certificate
  • generic datasets for appdata/pgData/userData

Collbora setup is default, I didn’t change anything:

I entered the collobra web adress in the next cloud office admin panel and get the checkmark:

Certificate validation is disabled.

Everytime I try to open a document, the error is the same:
Document loading failed

Now there seems to be tons of reasons why this is happening, but I still haven’t found out mine.

I looked through the following logs and couldn’t find anything:

  • Next cloud admin panel log
  • True nas scale next cloud container logs
  • collabora container logs

I found this post, which is similiar but also didn’t help me.

Is there someone who can still give some guidance?
