4K Video Downloader can't parse link error

Part 1: To get rid of those 4K Video Downloader errors, we should firstly figure out the reason why 4K Video Downloader can't download or can't parse links.

Reason 1 - Minor software bugs or compatibility issues.
When running 4K Video Downloader on computer, we may find it not working now and then due to a software or hardware malfunction. It's actually not a big deal and can be wiped away by the following software and hardware resets and alike.

Tick Solution:

  1. Upgrade 4K Video Downloader to the latest (4.12.1) version;
  2. Reboot computer;
  3. Run the application as administrator;
  4. Copy video link without "https://";
  5. Enable "Smart Mode";
  6. Change video download directory under Smart Mode;
  7. Reinstall 4K Video Downloader.

Reason 2 for 4K Video Downloader error - The video parsed is not supported by 4K Video Downloader
To begin with, you must make sure the video you wanna download is chosen from 4K Video Downloader supported websites - YouTube, Facebook, Vimeo, SoundCloud, Flickr, Dailymotion and Metacafe. Then, 4K Video Downloader can only access and download free video sources. That's to say, neither video from other hosting sites (like Instagram, Twitter and Lynda) nor video that is private (with password) or monetized (like YouTube Red) can be analyzed by 4K Video Downloader.

Tick Solution: Find free and public video on 4K Video Downloader supported sites to parse.

Reason 3 - 4K Video Downloader is blocked to connect to the Internet
To ensure a secure network implementation, the firewall and anti-virus program on your computer may stop Internet connection of 4K Video Downloader.

Tick Solution: Temporarily turn off firewall and antivirus software when attempting to download reliable videos from YouTube and more. Don't forget to turn security back afterward.

Reason 4 for 4K Video Downloader error - Your IP address is limited to visit the video site
When you moved to an area with (YouTube) video site blocking for some reason, it's impossible to take any video download successfully unless you seek help for proxy server.

Solution: 4K Video Downloader offers 4 proxy connection options for you to choose, web HTTP proxy, secure HTTPS proxy, SOCK4 proxy and SOCK5 proxy.

Reason 5 - 4K Video Downloader is outdated on downloading upgraded video.
Video sharing sites usually update their algorithms to prevent their video content from downloading. That's why VEVO videos on YouTube cannot be downloaded sometimes.

Tick Solution: Usually, you can throw this problem away by trying multiple times, waiting for a further software upgrade.
