4k video downloader

4k Video Downloader is a popular download tool used by millions of users. If you suddenly got an error while, for example, downloading a video from YouTube, it is either YouTube is down (most unlikely) or something related to the 4k Video Downloader version you have running on your device (most likely). This post covers the various error messages generated by the 4k Video Downloader software and feasible ways of fixing these errors.

Part 1. Which 4K Video Downloader errors may you see?

Various kinds of errors have been reported by users of 4k Video Downloader. The most common of these errors are:

Download Errors

4k download error

This error is usually indicated by "Error: Can't download" on the app.

Parsing Error

4k parse error

Of the major errors generated by 4k Video Downloader, this is the most common.

Crash Errors

This usually occurs when 4k Video Downloader crashes. Your operating system, in most cases, will inform you about the crash and possibly give more details of the crash.

Part 2. Fix 4K Downloader Cannot Download Error

4k Video Downloader requires an active internet connection to be able to download the video. If you're confronted by this error, first things first; try to check your internet connection as 4k Video Downloader would not work without an active internet connection. If you've confirmed that your device is properly connected to the internet, but 4k downloader can't still download videos, then try the following:

Firewalls and antivirus apps usually block some apps that send or download data from the internet for various reasons –for your protection. If you have any active firewall, open it up, and ensure 4k Video Downloader isn't locked out of internet access.

If you just installed 4k Video Downloader, you may need to restart your device before the app can initialize properly.

If other video programs are running on your device that you think could interfere with this app, close them.

This may not be obvious from the start, but videos wouldn't save when there's not enough space for your storage device. You can view your device's space with any good file manager.

Perhaps, your operating system is denying 4k from accessing the set download directory/destination. Changing this location (i.e., where downloaded videos are saved) may be able to fix this error.

In this case, if you can't fix it from your privacy settings, you may consider changing your proxy (in cases of blocked videos).

If you can't download videos or download abruptly ending at 99% or somewhere, use the guide below to fix this.

Steps to Fix Video Not Completely Downloaded (99%) With Recoverit Video Repair:

Your media players will usually not play any media file that wasn't downloaded up to 100%. Media players read/handle such files as corrupt media files. If a 4k Video downloader downloaded your video up to 99%, then the Recoverit Video Repair tool may just be able to fix the tail end.

Please follow the steps outlined below to fix your video file if it wasn't downloaded completely.

Part 3. Fix 4K Downloader Crash Error

If you were confronted by a software crash (of 4k Downloader), then your issue most likely isn't from your video. Software crashes are usually a result of a bug in the software, bugs in operating systems, or antivirus/firewalls force-closing apps. If 4k Downloader crashed, first ensure that it isn't black-listed by your firewall/antivirus software (if you have any installed). After checking, you should try the following:

  1. Check for updates and upgrade the 4k video downloader to the latest version available.
  2. Reinstall the software.
  3. Reboot your device (administrator mode)
  4. Enable "Smart Mode" from the 4k video downloader app.
  5. Ensure that the video URL can be accessed via HTTPS. If not; Replace https:// with http://

Part 4. Fix 4K Downloader parsing error

This error can be indicated by "Can't parse this link…", "Error. Unknown site…", "This site is unsupported", "Can't parse any video link…:" Etc…

As this error is usually a result of the 4k downloader not being able to parse the link provided, you should check the link to confirm it's accessible. Access the link with a working browser to make sure it is working before proceeding with your attempt. If parsing error persists, please try the following:

  1. Ensure that no firewall is actively blocking your apps from internet access.
  2. Reboot your device as an administrator.
  3. Update 4k video downloader to the latest version available.

Tried Everything and Error Persists?

If you've tried Running 4k video downloader as admin, uninstalled and reinstalled the app, ran the app in smart mode, changed the destination of download, confirmed that no firewall/antivirus is blocking access or entirely turned off firewalls, rebooted your device, and changed proxy/VPN then you should probably update your operating system and scan your entire device for virus infection. You should also contact a 4k video downloader from their official website to confirm the issue isn't from their website and that they support the website/server you are trying to download videos from.
