Hopefully I can explain my setup.

I am using cloudflare as a DNS server for my domain  
I have the following records

[nextcloud.example.com](http://nextcloud.example.com) for my nextcloud host  
[collabora.example.com](http://collabora.example.com) for my collabora CODE host  
both point to my server at home.  
This server is running Ubuntu with docker.  
Inside docker I have nginx as a reverse proxy to redirect the incomming request.  
all the scripts are shown below.

I can browse to nextcloud address, and nextcloud seems to be working properly.  
I have installed nextcloud office and configured it to contact through collabora address.  
The admin page of nextcloud office is showing the message “Collabora Online server is reachable”. I can create new office files inside the files app. The new file is being created.  
But when I want to open the file I get an error “Document loading failed  
Failed to load Nextcloud Office - please try again later”

i tried some debugging in chrome and got to this point where i think i get an error from cloudflare. I am not very experienced in all this and don’t know what this means. this is the consolde output when i try to open a document from within the nextcloud “file” app.

Also I noticed that the websockets do not work with the nginx config from the collabora webpage.

Yesterday I changed from the latest docker image of collabora/code to 24.04.12.4.1 and all of the sudden it works.  
Can someone explain way this would be the case? I am very happy though.

One thing I do notice is, when I create a new file, it’s is immediately created and opened. This always results in an error.  
If I wait a little and open the file from nextcloud ‘file’ app it opens correctly like the server needs some time to prepare the file…

I tried different docker images but everyone \>= 24.04.13.1.1 seems to fail
