Describe the Bug

Hello there!

I have been using the latest Nextcloud AIO (Unraid "Homelab") with Pangolin 1.12.3 (OVH VPS) without any problems. Today I did the upgrade to Pangolin 1.13.0 with all requirements, including Traefik from 3.6.2 to 3.6.4. After the upgrade I thought everything went fine, as usual. I was able to log into Nextcloud and use mostly everything. Strangely, I am unable to use Nextcloud Office (Collabora) anymore, and shared calendars won't work either. I am unable to open up or create a document, nor am I able to write an appointment into the calendar. The sync from smartphone via DAVx does not work and shows a 400 error. I get a WebSocket error if I want to open Collabora and add an appointment. I restored an update of the VPS from earlier today, so I am back to Pangolin 1.12.3. Furthermore, I did not change anything with Nextcloud, and all is running just fine.

I've been using Pangolin for around 2 months now and did every upgrade without trouble. I am not sure why the latest version causes problems with WebSocket.

Environment

OS Type & Version: Ubuntu 24.04.3 LTS
Pangolin Version: 1.13.0
Gerbil Version: 1.3.0
Traefik Version: 3.6.4
Newt Version: 1.7.0
Olm Version: (if applicable)

To Reproduce

Just upgraded from 1.12.3 to 1.13.0 with all requirements.

Expected Behavior

Nextcloud Office should open up, and there should be no syncing problems with the Nextcloud calendar.
