What "Could Not Load Video" means and why it happens
When you see "Could Not Load Video" on a website, the browser tried to play a video file but something broke the connection between your device and the server holding that file. This is not usually a problem with your internet speed — it is almost always one of five specific things: the video file itself is corrupted or missing, your browser does not support the format, your connection dropped mid-load, the website's server is temporarily down, or your device ran out of memory while trying to play it.
Websites store videos on servers, and your browser has to read that video data in real time as you watch. If any step in that chain fails — the server stops responding, your connection stutters, the file format is not compatible — the video stops and you see an error. The good news is that most of these problems are fixable in under five minutes, and you do not need technical knowledge to try the solutions.
Key Takeaways
- Most video errors come from browser cache problems, incompatible formats, or a temporary connection hiccup — refreshing the page fixes the majority of them.
- If refreshing does not work, clear your browser cache and cookies, because old cached video data can conflict with new playback attempts.
- Switching browsers or devices tells you whether the problem is specific to your setup or a real problem with the video itself.
- If the video works on another device but not yours, the issue is almost always your browser, extensions, or device memory — not the website.
- Website owners can see video errors in their logs, so reporting the problem with your browser name and device type helps them fix it faster.
Refresh the page first — it solves most video errors
The fastest fix is to reload the page. Press F5 on Windows or Command+R on Mac, or click the refresh button in your browser's top left corner. Wait for the page to fully load before clicking play again. A refresh tells your browser to read the video file fresh from the server instead of using old, possibly corrupted data it cached the last time you visited.
If the video plays after a refresh, the problem was a temporary glitch — either your connection dropped for a moment while the video was loading, or the server had a brief hiccup. These happen constantly on the internet and usually fix themselves. If it happens again on the same video, move to the next step.
Clear your browser cache and cookies
Your browser stores copies of videos, images, and other files on your computer so pages load faster the next time you visit. Sometimes this cached data gets corrupted or conflicts with a new version of the video, and your browser tries to play the broken copy instead of downloading a fresh one. Clearing the cache forces your browser to read everything new.
In Chrome, Firefox, Safari, or Edge, press Ctrl+Shift+Delete (Windows) or Command+Shift+Delete (Mac). A window will open asking what you want to delete. Check the boxes for "Cookies and other site data" and "Cached images and files", then click Clear. Close the browser completely and reopen it, then try the video again. This usually takes two minutes and solves format conflicts and corrupted cache problems.
Try a different browser or device
If the video still will not play, open the same page in a different browser. If you normally use Chrome, try Firefox or Safari. If you have a phone or tablet nearby, visit the same website on that device. This tells you whether the problem is specific to your browser and device, or a real problem with the video file itself.
If the video plays in a different browser or on a different device, the problem is your original browser — usually an outdated version, a conflicting extension, or your device running low on memory. If the video fails on every browser and device you try, the problem is the website's video file or server, and you should report it to the website owner. If it plays on some devices but not others, the issue is usually that one device does not support the video format the website is using.
Check if browser extensions are blocking the video
Extensions that block ads, trackers, or scripts can sometimes block video playback by mistake. Open your browser's extension menu (usually a puzzle piece icon in the top right), and temporarily disable all extensions. Reload the page and try the video again. If it plays, one of your extensions is the culprit.
To find which one, re-enable extensions one at a time and test the video after each one. When the video breaks again, you have found the problem extension. You can then either remove it, update it, or add the website to that extension's whitelist so it does not block videos there. Most ad blockers and privacy extensions have a settings page where you can do this.
Restart your device and check your internet connection
If none of the above worked, restart your computer or phone completely. This clears your device's memory and closes any background programs that might be using bandwidth or processing power. While your device is restarting, check your internet connection by opening a speed test website like speedtest.net. Video playback usually needs at least 2 to 5 megabits per second depending on the video quality.
If your connection is much slower than that, move closer to your router or restart your modem and router. Unplug them for 30 seconds, plug them back in, and wait two minutes for them to fully restart. Then try the video again. If your connection is fine but the video still will not play, the problem is almost certainly the website's server or the video file itself.
Report the problem to the website if nothing works
If you have tried all the steps above and the video still will not play, the problem is likely on the website's side — either the video file is corrupted, the server is having trouble, or the file format is not compatible with most browsers. Look for a "Contact Us" or "Report a Problem" link on the website and send them a message. Include the name of your browser, your device type (Windows, Mac, iPhone, Android), and the exact URL of the page with the broken video.
Website owners have access to logs that show exactly what went wrong when you tried to play the video. With that information, they can fix the file, re-upload it, or convert it to a format that works better. The more specific you are about what you tried, the faster they can solve it.
Frequently Asked Questions
Does a slow internet connection cause video errors?
Slow connections cause videos to buffer or pause, but usually not a "Could Not Load Video" error. That error means the browser could not reach the video file at all, not that it is loading slowly. If your connection is under 2 megabits per second, videos may struggle, but try refreshing first — sometimes a slow connection just needs a second attempt.
Why does the video work on my phone but not my computer?
Different devices and browsers support different video formats. Your phone might play a video in a format your computer's browser does not recognize. Try updating your browser to the latest version, or try a different browser on your computer. If that does not work, the website may need to offer the video in multiple formats.
Will clearing my cache delete my passwords?
Only if you check the "Passwords" box when clearing. When you clear cache to fix a video, uncheck that box and only clear "Cached images and files" and "Cookies and other site data". Your saved passwords will stay safe.
What if the video loads but plays with no sound?
Check your device's volume first — it may be muted. Then check your browser's volume by looking for a speaker icon on the video player itself. If the video has sound on other devices, your browser or device may have an audio issue. Restart your device and try again, or switch to a different browser.
Can I fix a video error on a website I own?
Yes. Check that your video file is not corrupted by trying to play it on your own computer. Re-upload the video to your hosting service, and make sure it is in a widely supported format like MP4 with H.264 video codec. Test it in multiple browsers before publishing. If errors persist, contact your web hosting provider — the server itself may be having trouble delivering the file.
