How to fix HTML5 video not found error?

Here are six fixes you can try out.

Restart your router

Power cycling your network equipment is the fix to more issues than you think. More often than not, connectivity issues can be caused by an underlying bug in your router and can be fixed by rebooting.

Try another browser

Another quick workaround for the problem is that you can try a different browser for the time being. This won’t fix the problem with your primary browser but can help you get the job done.

Update your browser

Often an out-of-date app or browser can restrict you from visiting certain websites. Update your browser and app to the latest version to see if it resolves the issue. 

Head over to chrome://settings/help and make sure you’re on the latest update. If you’re not, update immediately and try again.
