Fix 2: Check the URL of video.
If the video you want to download is from a playlist, directly copying the URL from the browser address bar could lead to download failure as well. Please right click on the video player to copy the URL.

Fix 3: Check if the website is supported.
If the video you want to download is from an unsupported site, the program may fail to analyze the URL.

Fix 5: Check if the website's encryption algorithm has changed.
Try some other videos from the same site and videos from other sites. Contact us if the downloader fails to work with certain videos or sites.

Sometimes, you can download videos from a site but fail to download some other videos from the same site. This is because some videos are DRM-protected and cannot be downloaded.

Fix 6: Clear the DNS resolver cache. The steps are as follows:

a> Close the software, press the Windows button and search "CMD" and open the Command Prompt window.
b> Type "ipconfig /flushdns" (no quotation marks) and click enter.
c> Launch the software and try downloading to see if it works now.

You may need to flush the DNS a few more times for it to work.

It usually takes no longer than one minute to analyze a URL. If the downloader have been analyzing the URL for a couple of minutes, you should cancel it and try the fixes mentioned.

Fix 2: Check if the downloader module is intact.

* For Windows 8 and later:
Step 1: Check if dl.exe and the _internal folder are in the following location. The downloader will not work if either is missing.

Step 2: Whitelist dl.exe in all your antivirus/firewall/VPN programs or temporarily disable them to see if it solves the problem. It's very common that some antivirus/firewall programs falsely see dl.exe as malware and block it.
