Not a single video is being played in any web, it is failing for twitter, reddit, etc. Youtube is working fine.

I have found the following message from reddit web code: "Uncaught (in promise) DOMException: The fetching process for the media resource was aborted by the user agent at the user's request."

I have found the solution:

• Open configuration and go to Apps
• Optional Characteristics
• Install Microsoft WebDriver, Windows Media Player and Media Feature Pack
