Why video downloads fail even when the video plays.

Common reasons a download fails

• DRM or protected streaming: The video is intentionally protected and should be requested as a proper delivery file.
• Login context: The page only works after signing in, and the downloader may need browser context for authorized access.
• Expired URLs: Some media URLs only work for a short time or only from one session.
• Preview-only links: A page may show a short preview while the full file is behind an account, purchase, or approval gate.
• Site changes: Websites change players and formats often, which can temporarily break extraction.

What to try first

Start with the simplest checks: update Luma Pull, retry the link, and confirm the media is actually downloadable under your access rights. If the page needs a signed-in session, try the built-in browser and use Pull Page after the media is visible.

When not to keep fighting it

If the content owner uses DRM, subscription controls, or a paywall, do not try to force it. Ask for a rights-cleared MP4, WAV, MP3, or delivery folder. That is cleaner legally, technically, and professionally.

What support needs

If a public or authorized link still fails, send support the app version, install source, output format, the failing URL, and a support bundle from the app. That gives enough context to identify whether the issue is site support, app behavior, or access rights.
