I tried to get ollective.collabora running on a test system.
Collabora is installed on https://collabora.zopyx.com, running internally on port 9980 and exposed via Caddy over https.
A Plone 6.1 site is running on https://collabora2.zopyx.com and has set collective.collabora.collabora_server_url=https://collabora.zopyx.com set.
This configuration caused the following Mixed Content error:
