Fix 3: Close Any Active Media Players Or Workstations

According to this Reddit thread, keeping a media player or digital audio or video workstation open while watching a Twitch stream can cause the 4000 Error.

As much as you might be accustomed to multitasking, it could be necessary to pause for a while to overcome the issue.

Reddit users have reported multiple programs that interfered with Twitch, so be sure to close any of these if they are open before trying to view a stream.

  • VLC Player (Media Player)
  • Reason Studios (Digital Audio Workstation)
  • Studio One (Audio Engineering Workspace)
  • FL Studio (Digital Audio Workstation)
  • Premiere Pro (Video Editing Software)
  • AVID (Video Editing Software)

These are some confirmed examples of programs that can interfere with Twitch and cause the 4000 error, but there could be many others.

It is worth closing everything on your PC, other than your Chrome browser, to verify if this is causing your issue.

Fix 4: Clear Browsing Cache And History

A few users mentioned that deleting their browsing cache and history resolved the Twitch Error 4000 for them.

If you haven’t done this recently, the accumulation might be causing the problem. If you are a Chrome user, here’s how to do it quickly.

  1. Open Chrome on your PC and click on the three vertical dots in the top-right corner.
  2. In the dropdown menu, choose Settings to open the configuration panel.

Fix 6: Uninstall Any Unnecessary Driver Software

The majority of modern gaming hardware, such as headsets and mice, includes dedicated software developed by the manufacturer. These programs allow you to change settings (DPI, Sound Modes, etc.) RGB settings, and other similar options.

They can offer extra advantages when using your machinery but may also result in problems.

Several Twitch users have reported that installing such software on their computers made the 4000 error appear. You should try closing them before loading a stream to see if the issue is being caused by those active processes.

In extreme cases, you might even need to uninstall these apps completely.

This also applies to related software such as “Driver Boosters” or “Game Boosters,” as they are known to interfere with other apps besides Twitch.

Fix 7: Set The Autoplay Policy To “Default” On Chrome

This is another simple yet effective fix. It might appear challenging, but by following the steps below, you can get it done in no time.

  1. Open Chrome on your PC.
  2. In the URL address bar, type “chrome://flags” without quotation marks. Press Enter on your keyboard.

  4. After finding the Autoplay Policy setting, change its value to default.

This should resolve the problem, which will let you continue watching Twitch streams without experiencing the 4000 error.

Fix 8: Use A Different Browser

Using a different browser is always an option. If Chrome or Firefox, the two most popular browsers, are causing problems, there are many alternatives that you can switch to, even if it’s only temporarily.
