Having researched this topic, it appears there are multiple reasons for users to encounter this inconvenient error while watching streams. Some of those possible causes are listed below.

You can manually click your browser’s refresh button or press the F5 shortcut on your keyboard.

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 used to multitasking, it could be necessary to stop for a while to overcome the problem.

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 check if this is causing your problem.  

Fix 4: Clear Browsing Cache And History

Some users reported that clearing their browsing cache and history helped them overcome the Twitch Error 4000.

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 that appears, 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 provide added benefits while using your hardware, but they might also cause issues.

Multiple 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 problem is being caused by those active processes.

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

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