Fixed this exact problem for a customer last Tuesday. ClipGrab had just stopped dead, throwing a 'download failed' message on every URL they tried. Took about 25 minutes to sort once we knew where to look. The fixes below go from the fastest possible check right through to a full clean reinstall, so start at the top and work down.
TL;DR
ClipGrab not working is almost always caused by an outdated version, a corrupted or zero-byte yt-dlp component, or a dead proxy sitting in the settings. Update ClipGrab first, disable any proxy, then replace the yt-dlp binary if needed. Most people are sorted within 15 minutes.
Key Takeaways
- ClipGrab not working is usually caused by an outdated app version or a broken internal yt-dlp engine.
- A proxy server configured in ClipGrab settings that has gone offline will block every single download attempt.
- Deleting the %appdata%\ClipGrab folder is safe and often clears the problem in one shot.
- SSL errors are frequently caused by a wrong system clock, not ClipGrab itself.
- A clean reinstall (uninstall, delete leftover folders, reboot, reinstall) fixes corruption that a simple update misses.

What Causes ClipGrab Not Working?
ClipGrab not working usually comes down to one of five things, and knowing which one you are dealing with saves a lot of time. The most common by far is an outdated app version. YouTube changes its internal structure regularly, sometimes weekly, and older ClipGrab builds simply can not keep up. The second most common cause is a corrupted or zero-byte yt-dlp binary sitting inside the app's data folder. ClipGrab relies on yt-dlp (YouTube-DLP) to actually pull video data, and if that component is broken, nothing downloads regardless of how good your connection is.
Proxy problems are sneaky. A lot of people set up a proxy in ClipGrab at some point and then forget about it. When that proxy goes offline, ClipGrab tries to route every request through it and fails silently. You see 'download failed' and assume it is a YouTube issue, when actually it is a dead proxy in your settings. Worth checking early.
SSL errors are a separate beast. If your Windows system clock is wrong by more than a few minutes, Windows rejects SSL certificate handshakes and ClipGrab sees a connection failure. Same thing can happen if your root certificates are out of date, which is why pending Windows updates sometimes matter more than people expect. And finally, there is plain old installation corruption: files that got mangled during a previous update, or a configuration cache that has gone dodgy over time. A clean reinstall sorts that.
URL format problems are less common but worth mentioning. Shortened links like youtu.be or bit.ly, playlist URLs, and links with timestamp parameters (the ?t=120 bit at the end) can all confuse ClipGrab. Always grab the full URL from the browser address bar and strip any extra parameters before pasting it in.
ClipGrab Not Working: Quick Fixes
These three steps fix the problem for the majority of people. Do them in order before touching anything else.
Update ClipGrab to the Latest Version Easy
- Close ClipGrab completely
Right-click the taskbar icon if it is running in the background and choose Exit or Quit. Do not just close the window. - Download the latest installer
Go to clipgrab.org and grab the current Windows version. The official FAQ specifically states that new versions fix problems present in older builds. - Run the installer over the top of your existing install
You do not need to uninstall first for a simple version update. Let the installer overwrite the old files. - Reopen ClipGrab and test a download
Paste a full YouTube URL and try. If it works, you are done.
Disable the Proxy Server in ClipGrab Settings Easy
- Open ClipGrab and go to Settings (or Preferences)
Look for a Proxy server section. It might be tucked under a Network or Connection tab depending on your version. - Disable any active proxy
If a proxy address is filled in and the option is enabled, turn it off. Leave the field blank unless you specifically need a proxy for your network. - Retry your download
An offline proxy causes every download to fail immediately. Disabling it often fixes ClipGrab not working in seconds.
Check Your URL and Try a Different Format Easy
- Copy the full URL from your browser address bar
Avoid youtu.be links, bit.ly links, or anything with playlist parameters (list=...) or timestamps (?t=120). Use the full https://www.youtube.com/watch?v=... format only. - Paste the clean URL into ClipGrab and retry
If it still fails, open the Format selector and switch from MP4 to WMV or MP3 and try again. Some format-specific issues clear when you change the output type.
Intermediate ClipGrab Not Working Fixes
Still getting ClipGrab download failed errors after the quick fixes? These steps go a bit deeper. The yt-dlp fix in particular is one that most guides miss, and it is the actual root cause more often than people realise.
Reset ClipGrab Configuration and Cache Easy
- Press Win + R, type
%appdata%and press Enter
This opens your Roaming profile folder in Windows Explorer. - Find the ClipGrab folder
Right-click it and rename it toClipGrab.old. This keeps a backup without deleting anything permanently. If you would rather just delete it, that is fine too. - Restart ClipGrab
It will recreate the folder with fresh default settings. You may need to re-enter any preferences you had set previously. - Test a download
Corrupted settings and cache are a surprisingly common cause of ClipGrab not working, and this clears them completely.
Replace the Corrupted yt-dlp Component Medium
- Close ClipGrab
Make sure it is fully closed, not just minimised. - Press Win + R, type
%appdata%and press Enter
Open the ClipGrab folder, then open the subfolder also named ClipGrab inside it. The path will look likeC:\\Users\\YourName\\AppData\\Roaming\\ClipGrab\\ClipGrab. - Check the yt-dlp file size
If you see a file named yt-dlp (or yt-dlp.exe) with a size of 0 KB, it is corrupted. Delete it. - Download the current yt-dlp binary
Go to the official yt-dlp releases page on GitHub and download the latest yt-dlp.exe for Windows. - Place the new binary in the ClipGrab folder
Drop the downloaded yt-dlp.exe into the sameClipGrab\\ClipGrabsubfolder where the old broken file was. - Restart ClipGrab and test
A fresh yt-dlp binary almost always fixes persistent ClipGrab download failed errors that survive an app update.
Fix SSL and Connection Errors Medium
- Check your system clock
Go to Settings, then Time and Language, then Date and Time. Make sure Set time automatically is on, then click Sync now. An incorrect clock is the most common cause of SSL handshake failures in ClipGrab. - Disable VPN or corporate proxy temporarily
If you use a VPN, disconnect it and test ClipGrab on your normal connection. Same goes for any system-wide proxy settings in Windows. - Try a different network
Connect your PC to a mobile hotspot and test ClipGrab. If it works there, your ISP or router firewall is blocking something. - Run ClipGrab as administrator
Right-click the ClipGrab shortcut or ClipGrab.exe and select Run as administrator. Permission issues can cause network access failures that look like SSL errors.
If you are dealing with broader network issues on Windows, our guide on fixing Windows network connection problems covers firewall rules and DNS settings that can affect apps like ClipGrab.
Advanced ClipGrab Not Working Fixes
These are for the stubborn cases. If you have been through everything above and ClipGrab is still not working, something deeper is wrong. A full environment reset clears out every legacy file and config that might be overriding the new installation. It is a bit more work but it is the nuclear option that sorts things when nothing else does.
Full Clean Reinstall of ClipGrab Medium
- Uninstall ClipGrab via Windows Settings
Go to Settings, then Apps, then Installed Apps (Windows 11) or Apps and Features (Windows 10). Find ClipGrab, click it, and choose Uninstall. - Delete leftover installation folders
Open File Explorer and checkC:\\Program Files\\ClipGrab. If the folder is still there after uninstalling, delete it manually. - Delete the AppData folder
Press Win + R, type%appdata%and press Enter. Delete the entire ClipGrab folder. This removes all cached settings, the old yt-dlp binary, and any corrupted config files. - Reboot Windows
Do not skip this. A reboot clears any file locks and ensures Windows is not holding onto old ClipGrab processes in the background. - Download and install the latest ClipGrab
Get it fresh from clipgrab.org. Run the installer and let it complete fully. - Verify the yt-dlp component after install
Press Win + R, type%appdata%\\ClipGrab\\ClipGraband press Enter. Check that a yt-dlp file is present and has a non-zero file size. If it is 0 KB, replace it with the current binary from GitHub as described in Solution 5. - Test a download immediately
Do not change any settings first. Paste a full YouTube URL and try. If it works on default settings, you can then reconfigure preferences carefully.
Windows Firewall and Security Software Check Medium
- Open Windows Security and check Firewall settings
Go to Windows Security, then Firewall and network protection, then Allow an app through firewall. Make sure ClipGrab is listed and has both Private and Public ticked. - Temporarily disable third-party security software
If you run Malwarebytes, Bitdefender, Norton, or similar, disable real-time protection briefly and test ClipGrab. Some security tools block downloader apps by default. If ClipGrab works with the security software off, add it to the exclusions list rather than leaving protection disabled. - Test with a new Windows user account
Go to Settings, then Accounts, then Other users, and add a new local account. Log in, install ClipGrab fresh, and test. If it works there but not your main account, the issue is profile-specific corruption rather than a system-wide problem.
Security software blocking legitimate apps is something we see a lot. If you are having broader issues with apps being blocked on Windows, our article on fixing Windows Firewall blocking applications walks through the exclusion process in detail for the most common security suites.
And if you are running into problems that seem tied to a specific Windows user profile rather than the whole system, take a look at our guide on repairing a corrupted Windows user profile. Profile corruption is more common than most people realise and it causes all sorts of weird, hard-to-trace app failures.
According to Microsoft's guidance on Windows time settings, keeping your system clock synced is essential for SSL-dependent applications. It is one of those things that sounds too simple to matter, but it genuinely causes ClipGrab SSL errors and connection failures more than you would expect.
Preventing ClipGrab Not Working
Most of these problems are avoidable. Here is what actually makes a difference, in order of importance:
Keep ClipGrab updated. This is the big one. YouTube changes frequently, and ClipGrab not working is almost always the result of running an old version. Make it a habit to check for a new version every few weeks. It takes two minutes and prevents the majority of download failures.
Back up your working AppData folder. When ClipGrab is working properly, copy the %appdata%\ClipGrab folder somewhere safe. If things break later, you can restore it instead of starting from scratch. Sounds overly cautious but it has saved a lot of time for people who download regularly.
Leave the proxy setting off. Unless your network specifically requires a proxy, keep it disabled in ClipGrab settings. Configured proxies that go offline silently are one of the most common causes of ClipGrab download failed errors, and they are easy to forget about.
Use full URLs only. Always copy the complete URL from the browser address bar. No shortened links, no playlist URLs, no timestamp parameters. This takes about three extra seconds and eliminates a whole category of ClipGrab not working errors.
Keep Windows updated. Root certificate updates come through Windows Update and directly affect whether ClipGrab can form SSL connections. Do not ignore update prompts, particularly cumulative updates.
ClipGrab Not Working: Summary
ClipGrab not working is almost always fixable without reinstalling Windows or switching tools. The vast majority of cases come down to an outdated app, a corrupted yt-dlp binary, or a dead proxy in the settings. Start with the quick fixes: update ClipGrab, disable any proxy, and check your URL format. If ClipGrab download failed errors persist, reset the AppData folder and replace the yt-dlp component. For anything more stubborn, a full clean reinstall with a fresh yt-dlp binary sorts it. SSL errors are usually a clock or Windows update issue rather than ClipGrab itself. Work through the tiers in order and you will be sorted.
