Missing Preview Images for Nextcloud Talk Links (e.g., in WhatsApp or Social Media)

Hello everyone,

I am currently facing an issue with my Nextcloud Talk instance that I can’t resolve. The problem is about the preview that is usually generated when sharing links in WhatsApp or other social networks.

What works: When I share regular sharing links from my Nextcloud (e.g., for files or folders), a preview image is generated correctly. The title and description are also displayed.

What doesn’t work: For Talk links (e.g., https://meet.example.com/call/xyz123), the preview is completely missing. Instead, only the plain link is shown, without an image, title, or description. This doesn’t look good and might confuse other users.

Questions:

  1. Is there a possible configuration in Nextcloud to enable Open Graph tags for Talk links?
  2. Should I make changes directly in the spreed code? If so, where exactly would it make sense?
  3. Do specific Nextcloud privacy settings block the creation of preview images for Talk links?
  4. Has anyone encountered a similar issue or found a workaround?

I would appreciate any ideas or suggestions on how to solve this problem. Thank you in advance!

Best regards,
Zehirlioglu
