Video Download Troubleshooting: A Step-by-Step Checklist

A failed download does not always mean that the video is unavailable. The cause may be an expired browser session, a changed page address, a temporary network problem, or a format that the source no longer provides. Work through these checks in order.

1. Confirm the page is accessible

Open the original page and play part of the video.

• If it was removed, made private, or blocked in your region, a downloader cannot retrieve it.
• If the page asks you to sign in, complete sign-in before submitting it again.
• If the URL came from a redirect or search result, open the final video page first.

This separates source-page problems from download-tool problems.

2. Refresh the browser session

Authenticated pages often rely on short-lived session data. Reload the page, reopen the UniGrab extension, and submit the request again. If you recently changed accounts or completed a verification prompt, use a fresh page instead of an older tab.

3. Try a compatible format

If the highest resolution fails:

1. Try 1080p or 720p.
2. Prefer MP4 and H.264 for a compatibility test.
3. Try audio-only when you only need the sound.
4. Keep enough disk space for temporary and final files.

High-resolution sources often provide video and audio separately. UniGrab uses FFmpeg to merge compatible streams.

4. Check the destination

Confirm that the folder exists and your account can write to it. Avoid unstable removable drives and network folders. Review security software history before changing protection settings.

5. Rule out the network

Pause other large transfers and retry. A proxy, VPN, DNS filter, or unstable wireless connection can interrupt long downloads. Failure at the same point may indicate a format problem; random failures more often indicate the network path.

6. Collect useful details

Update UniGrab before reporting a repeatable issue. Record the website, page type, selected format, time, exact error, and whether the page plays in the browser. Never publish private URLs, account cookies, or personal media.

Following this order usually identifies the failing layer quickly.
