👉To update your Google Chrome browser, follow these steps:

• Select Help and choose About Google Chrome.

• If you’re not using the latest version, click Relaunch to update Google Chrome. If you don’t have the option, it means you’re using the updated version.

Sometimes, updating the browser may not solve the “HTML5 video file not found” issue. The problem could be associated with your browser’s settings. Reset the settings to default, so it can play video with HTML5.

👉Follow these steps to disable hardware acceleration:

• Open Google Chrome and click the three dots at the upper-right corner.

When you initiate the Safe Mode in your browser, certain settings changes will be made, such as:

• The hardware acceleration will be automatically turned off.
• All plug-ins and add-ons will be disabled.

If a video with HTML5 plays without any error or interruption in Safe Mode, you should check the browser for the changed settings to note where the problem is coming from.

👉Here’s how to fix HTML5 video not found by restarting the browser in Safe Mode:

• Open Google Chrome and click the three dots at the top-right corner.
• Select More Tools and click Extensions.
