Bug description
Dear Nextcloud Support Team,
I am experiencing an issue with file previews when sharing entire folders using Nextcloud 29.0. Specifically, the problem occurs with previewing images within the shared folders. Instead of displaying the previews, a 404 error is returned.
Issue Details:
- Environment: Nextcloud 29.0 with Traefik
- Error URL: https://nextcloud.aronhome.com/apps/files_sharing/publicpreview/NdKjeBr6o85G6HS?fileId=11586290&file=%2F%E5%8F%96%E5%BE%97%E6%8C%96%E7%A4%A6%E8%BA%AB%E5%88%86%E7%A2%BC.docx&c=01282a98b34307355f43f172ab391976&x=469&y=469
- Error Message: 404 Not Found
- Share link: https://nextcloud.aronhome.com/s/NdKjeBr6o85G6HS
Steps to reproduce
- Share a folder containing images via a public link.
- Attempt to preview an image within the shared folder using the public link.
- Observe that the image preview fails to load, resulting in a 404 error.
This issue significantly impacts the usability of shared folders, as recipients cannot preview the contents of the shared files.
Expected behavior
When sharing a folder containing images via a public link, I expected that the images within the shared folder would be previewable. This means that clicking on an image in the shared folder should display a preview of the image, without any errors or issues.
This issue significantly impacts the usability of shared folders, as recipients cannot preview the contents of the shared files.
