I guess it is related to the same issue I open in Collectives : nextcloud/collectives#1645

Of course the folder .attachments.36071 does exist and the file AppNextcloudUtilisation.mp4 exists in it and can be loaded, the video works.

Thanks, that would of course make a lot of sense to have an inline viewer. I'm wondering if we can just make use of the viewer app for that to have the same logic for displaying any supported filetype.
