Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can 
Nextcloud version (eg, 20.0.5): 23.0.0
Operating system and version (eg, Ubuntu 20.04): Ubuntu Server 21.10
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.48
PHP version (eg, 7.4): 8.0.8
The issue you are facing:
I am self hosting Nextcloud on a Proxmox server and have run into a weird issue. I wanted to experiment with Nextcloud Office for a local volunteer organization so I created an Ubuntu 21.10 LXC unprivileged container, put it behind my Caddy reverse proxy, and started testing. I ran into my fair share of hiccups but eventually got it to the point where everything is working smoothly, all checks pass in the “Administration/Overview”, and I get an A+ on the Security Scan. It is publicly reachable at cloud.test.net (Not the actual URL) and I can create, share, and work with Office documents just like I was hoping to.
Since this is using my testing domain name I spun up another LXC from the same Ubuntu 21.10 base image using cloud.production.com (Again, not the actual URL) and configured it exactly the same way as the test instance, other than passwords and usernames. However, I cannot get Office working on this. As soon as I click “Download and Enable” on Collabora Online the interface locks up. I did a lot of Googling and found some folks recommending an older version of Collabora and CODE, so I tried v4 of Collabora and V6 of CODE. This did not help. The only way to recover that I have found is to roll the container back to a previous snapshot.
I have gone over both systems and cannot find any difference between their configuration. They are running identical versions of Nextcloud, Apache, and PHP, and I have diff’d the configuration files to confirm there is no difference other than the server names.
I am hesitant to abuse the working instance too much. At one point it randomly stopped working correctly as well, but rather than locking up it simply made me download the file instead of allowing me to edit it live. Fortunately I have automated snapshots and was able to roll back to the last and it worked again.
Is this the first time you’ve seen this error? (Y/N): Yes and No. I can reproduce it at will by rolling back to a pre-install attempt snapshot.
Steps to replicate it:
- Install Nextcloud 23.
- Install CODE
- Install Collabora Office
The output of your Nextcloud log in Admin > Logging: This is from before attempting to install Collabora Online. Once I try I am no longer able to access this log to see what, if anything, might have been added.
