Hey @nightcobe just a small heads up, before you drive yourself nuts, like I did 😁

I used Collabora since at least Nextcloud 28 without any issues.  
Since version 30.0.3, I have the same strange issues.  
[See my other forum post](https://help.nextcloud.com/t/collabora-preview-generation-memory-leak/212470/3)

I also tried to check with the great writeup of @wwe to hunt down the issue.  
But no luck.

I also use CODE and these two links

worked perfectly fine, but I still get the curl connection timeouts.

I did not have the knowledge or the time to further troubleshoot this, but just so you are aware that this might be a bug and not a config error on your side.
