Description

Hi all,

sometimes I getting randomly this kind of error on a clean nextcloud install with richdocuments (collabora) installed. I don´t even have photos. Everything is reachable via curl and I also don´t have any kind of restrictions. Using Traefik as proxy.

Research direction

Start by reproducing the preview conversion request to https://collabora.example.de/cool/convert-to/png with curl, then compare behavior through the Traefik proxy. The issue is complete when the intermittent 400 response is explained and preview conversion works reliably on a clean Nextcloud installation with richdocuments and Collabora.
