How to Fix Frequently-asked 4K Video Downloader Errors?

2. Error, can't download/remux.

3. This site is unsupported.

4. The valid link was not found in the clipboard.

5. Paring window never ends.

6. A heap of 0 bytes’ videos

7. Crash, Stuck or Freeze

Case 1. Poor Network Connection

Solution: Undoubtedly, 4K Video Downloader requires a good network connection. To diagnose this problem, firstly, check your other programs or frequently visited websites to see if they work well. Examine the network connection status, if needed, restart the router/modem or take a network reset and try it again.

Case 2. Prevented by Antivirus or Firewall

Solution: The Antivirus or Firewall will prevent unauthorized access to your computer network. Try to turn them off or add 4K Video Downloader to the whitelist to authorize the permission.

Case 3. Not Supported Website

Solution: Currently, 4K Video Downloader only supports YouTube, Facebook, Vimeo, SoundCloud, Flickr, Dailymotion, Metacafe, Twitch (recorded VOD streams), TikTok, Likee and some adult websites. If your pasted website hasn't been supported yet, just send a feedback or request to 4K Video Downloader official. But do not be that optimistic about the improvement progress, which may be postponed without specific time.

Case 4. Invalid Link in an Incorrect Format

Solution: Copy the link from browser address bar and ensure that the link you copied is complete without redundant long-tailed characters. If necessary, copy the link without "https://" or "http://".

Case 5. Accidental Crash and Freeze

Solution: This is a doomed problem that no piece of software can avoid. And the solution is nothing else than reinstalling 4K Video Downloader, reboot computer, run as administrator, etc. It's beyond the understanding, but surprisingly workable.

Case 6. Downloaded Videos are 0 Bytes and Won't Play

Solution: 4K Video Downloader won't prompt you that the storage space is insufficient. Make sure there is free disk space on your computer. You can change the destination before the download process, or switch to Smart Mode and customize the directory.

Case 7. The Downloaded Video is Private, Blocked, Age-restricted or Geo-restricted

Solution: Make sure the video is fully public and available even for unregistered visitors, you cannot download private video from other people. For your own private video, switch it from private to public or unlisted. In addition, use a VPN or proxy service to download blocked videos. You can fix it by opening "Preference" window > "Connection" > Enable "Proxy" option. 4K Video Downloader supports HTTP, HTTPS, SOCKS4 and SOCKS5 protocols.

Case 8. Only YouTube Download Doesn't Work

Solution: If it works well except for YouTube, your IP address is probably banned by YouTube due to overuse. Try to connect to another Wi-Fi spot or use any VPN utility to change IP, and try to unblock YouTube. If there is still no luck, it might also be caused by YouTube new algorithm, which always makes many video download software or website unusable. You have to report it to 4K Video Downloader support and wait for the new update.
