MatterMost Website Link Previews no Longer Working

Hello Everyone! I hope this finds you all well.

My goal is to get link previews working again. They used to work until the latest Mattermost Yunohost update 5.39-yuno

Issue: Link previews of Websites (youtube, articles, websites) are no longer working

Action: Post a link in a channel. https://www.gaia.com/
Expected results: Preview to the link with thumbnail and title, such as picture below:

RESULTS : NO LINK PREVIEW, doesnt work for any links any more.

failed solutions:

  • Link previews are enabled in system console
  • Rebooted Mattemost instance
  • Link previews are enabled in account settings under display
  • Searched for similar issues in mattermost - no luck with their solutions (all claiming v5.30 fixed Youtube and Twitter links)
