Are you getting a black screen with "Error #4000" code on Twitch? Here is a super simple fix that anyone can do. No more broken Twitch!

Error codes on Twitch may look scary when you first encounter them, but most of the time, they’re very easy to solve!

The reasons for running into an error on this online entertaining platform vary all the time. Sometimes it’s a bug on their end, and sometimes it’s a faulty extension or third-party software on our PC that’s causing the problem.

The Twitch Error 4000 problem – Black screen and interrupted media playback.

Luckily, the solutions are always here, and there’s nothing to worry about.

In the guide below, we’re solving the Twitch Error 4000 – Resource Format Not Supported Error, so if you’re dealing with this, now is the right time to learn more.

What Exactly Is The Twitch Error 4000?

Based on the number of Google searches, active Reddit threads, and opened topics on Twitch forums regarding this problem, it’s safe to say that users are indeed really confused with the 4000 Error on the platform.

This is perfectly understandable as these numbers don’t mean anything to someone who isn’t a developer at Twitch. So, what exactly is the 4000 Error on Twitch?

We researched this topic, and it seems like there are multiple reasons viewers encounter this inconvenience while watching streams. Here are some of them.

  • The viewer had another media player or a digital audio workstation opened in the background.
  • A hardware interference (usually audio-related) caused the error.
  • A new driver or software was installed recently.
  • Using a browser with piled up cookies and cache.

Although most of these things are considered perfectly normal, for some reason, they’re causing the Error 4000 on Twitch.

So, to get rid of this problem, you will have to “sacrifice” a bit of your freedom while watching Twitch. Luckily, the solutions are easy to do and don’t take much of your time.

Fix 1: Refresh The Stream

This is the easiest fix which is why you should try it as the first solution. Refreshing the stream takes less than five seconds, and some users confirmed that it helped them solve the Error 4000 problem.

You can manually click on the refresh button or use the F5 shortcut on your keyboard.

If the window refreshes successfully but the stream still doesn’t play due to the 4000 error, move on to the other fixes.

Fix 2: Pop-Out The Twitch Player

Another quick fix is to pop out the Twitch player. Follow the steps below to do so.

  1. Open Twitch.tv on your browser of choice. You don’t need to log in.
  2. Load up the stream you want to watch.
  3. Click on the cogwheel icon and choose “Popout Player” from the menu.

Now, try watching the stream in the popped-out window. It should work normally, and you shouldn’t encounter the 4000 Error.

Fix 3: Close Any Active Media Players Or Workstations

Some of us love to multitask, especially if our PCs are built for it. Producing music or editing a video while watching a stream on your other screen is perfectly normal. However, Twitch sometimes disagrees with this.

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

So, as much as we’re used to it, aborting our multitasking for some time is necessary to overcome the problem.

Reddit users reported multiple programs that interfered with Twitch, so make sure to close all of these if you have them open on your system!

  • 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)

Although these are some confirmed examples, the list of programs that might interfere with Twitch and cause the 4000 error could include more items.

Ultimately, you can close everything on your PC except your Chrome browser window to see if the issue lies in this.  

Fix 4: Clear Browsing Cache And History

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

If you haven’t done this in a long time, the pileup might be the root of the problem. So, for Chrome users, here’s how to do this quickly.

  1. Open the browser on your PC and click on the three vertical dots in the top-right corner.
  2. From the dropdown menu that shows, choose Settings to open the configuration panel.
  3. Scroll down a bit until you see the Privacy and Security section. Choose Clear Browsing Data to access the final window where you’ll be doing the cleanup.
  4. Here, tick all the boxes next to the three options available, as shown in the image below. Then, finish by clicking on Clear Data in the bottom-right corner. Make sure to select All-Time in the time range field.

Restart your browser and open Twitch once again. You should be able to watch a stream without experiencing the Twitch 4000 Error.

Fix 5: Plug And Unplug Audio Hardware

Some of us use headsets, while others use speakers. No matter your preferred way of hearing sound from Twitch streams, changing the port into which your audio device is plugged in might completely solve the issue for you.

If you have multiple free ports on your PC, you can try them all. Below, you can see an image of another confirmation for this solution, and you can find the full thread here.

Fix 6: Uninstall Any Unneeded Driver-Like Software

Most modern gaming hardware pieces, such as headsets and mice, come with dedicated software developed by the manufacturer. These computer programs allow you to change settings (DPI, Sound Modes, etc.) and RGB settings, and other similar options.

We benefit from installing these, but here’s where things get tricky.

Multiple Twitch users stated that installing such software on their computers made things worse regarding the 4000 error. So, you can try closing them before loading up a stream to see if the problem lies in those active processes.

In some cases, you might even have to uninstall these apps entirely.

The same thing applies to software such as “Driver Boosters” or “Game Boosters” as they are known to interfere with other apps as well, not just Twitch.

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

Another simple yet effective fix. At first, it seems like it’s challenging to do, but by following the steps below, you will get it done in no time.

  1. Open Chrome on your PC.
  2. In the URL address bar, type in “chrome://flags” without quotation marks. Hit “Enter” on your keyboard.
  3. A panel with many different experimental options will open. You’ll need to find the one called “Autoplay Policy” by either using the built-in search option in the panel or the Ctrl + F function.
  4. Upon finding the Autoplay Policy setting, change its value to default.

This should take care of the problem, and you should be able to 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 widely-used browsers, are giving you problems, there are many other alternatives that you can switch over to, at least temporarily.

In one of our guides, we cover all major browsers compatible with Twitch, so if you are out of ideas, feel free to take a look as it might be of good use to you. 

Fix 9: Download The Twitch Desktop App

Twitch has a desktop app that you can download for a very similar watching experience with slightly fewer bugs.

You won’t need to re-learn anything about Twitch since the interface is very similar to the actual website, and the entire design is relatively user-friendly.

Conclusion

Those are all the currently-known fixes for the 4000 error. None of them require the user to be tech-savvy, so feel free to try them out on your own by following the instructions listed in the guide above!

Hopefully, after completing a few of them, you will be able to watch streams without any further interruptions.
