The media could not be loaded because the format is not supported

Have you, at any point, encountered The media could not be loaded, either because the server or network failed or because the format is not supported error while trying to watch a video on the Internet?

Are you looking for a quick fix for this error? This tutorial got you covered!

What to do if the media could not be loaded?

  1. Switch to Opera
  2. Update your web browser
  3. Disable Adblock on your browser

1. Switch to Opera

If you don’t know what browser to download on your computer, we recommend Opera. This browsing solution is based on Chromium architecture. It has native support for webM – a modern, high-quality, and open video format. It also has built-in support for Ogg Theora video codec.

There’s another format out there the H.264 codec which is supported only by certain browsers. For all web developers out there, it means that you should offer the same video in two different formats. Doing so will ensure 100% compatibility.

You won’t experience any video buffering issues since this browser automatically blocks trackers, ads, and other elements that may cause slow browsing problems.

As a bonus, it also has Video pop-out: a floating video window that is adjustable

It also has a bunch of neat features to increase your productivity such as:

  • Sidebar integration with Messenger, Instagram, WhatsApp
  • Workspaces – to group tabs together and be more organized
  • Search in tabs – recently closed ones as well as those opened
  • free VPN

2. Update your web browser

  1. Open the Chrome browser on your PC.
  2. On the menu window (homepage), navigate to the upper right-hand corner and locate Options (illustrated by 3 dots).chrome browser the media could not be loaded either because the format is not supported
  3. Click on the Menu icon and then click on Settings.settings menu the media could not be loaded either because the format is not supported
  4. At the left side of the settings page, click on the Hamburger icon.settings menu the media could not be loaded either because the format is not supported
  5. Select the About Google Chrome from the menu.
  6. From here, the browser will automatically check for available updates and install them directly.check for updates chrome the media could not be loaded either because the format is not supported

More often than not, when you get The media could not be loaded, either because the server or network failed or because the format is not supported error, the actual cause could be that you are running an outdated browser.

In this case, the ultimate solution would be to update your web browser to the latest version, after which you should be able to load and watch the affected media/video.

Once this is done, go back and try to load the affected video again. If you are able to load/play it, then you are all set; otherwise, you can try the next fix.


3. Disable Adblock on your browser

  1. Open Chrome and go to the website that gives you this error message.
  2. Click on the Options icon.
  3. Locate and click on the ABP (AdBlock) icon.
  4. Disable AdBlock by clicking on the Block ads icon.
  5. Refresh the page.

Check if the video can now load. If the error persists, the problem is probably network-related (and not from your end), in which case there is little or nothing you can do about it, except to keep trying.

However, if you are running a web server that does not support certain video formats (like MP4, OGG, WebM, and such) you might have to reconfigure your server, to offer support for those video formats.

At times, some sites use this error as a smokescreen to trick you into disabling any ad-blocking feature on your browser. Most times, the video you are trying to watch contains some ads, and your browser (with an ad blocker) would not be able to play this video. This will result in The media could not be loaded, either because the server or network failed or because the format is not supported error.

There are various ways of enabling/disabling AdBlock, depending on the browser. And for convenience, we’ll be showing you how to disable it on Google Chrome.

You can simply disable AdBlock on the affected video’s host site, in order to gain access to the video.


The error message The media could not be loaded, either because the server or network failed or because the format is not supported is usually associated with an unsupported format, and in most cases, you should be able to fix this problem using one of our solutions.
