How to fix
Twitch Error 4000
on Windows

Hey, I have been struggling with Twitch recently. No matter which streamer I watch, I occasionally get an error #4000, which also says that the video is either unavailable or not supported. I haven't made any changes to my Windows PC recently, so I am not entirely sure why the problem started and why it is coming back. Any advice on this would be appreciated.

Twitch is the largest live streaming platform that specializes primarily in gaming. From regular gaming enthusiasts who want to share their gaming experience with the audience to large e-Sport events - it has it all. The service also provides a platform for other gaming-unrelated categories such as politics, sports, arts, music, and more.

Twitch is a diverse platform that provides hours of free entertainment for all kinds of people, hence why it is so popular. According to the statistics for 2022, the platform has over 140 million monthly users, with 30 million logging in to check out the streams daily.[ref en-1] With such popularity, things are bound to go wrong sometimes, and Twitch Error 4000 is one of the most common issues viewers encounter.

Users may encounter the error at any time while viewing a stream or when attempting to start it. In fact, the behavior is very similar to other Twitch errors, including error 2000. The message delivered to users reads as follows:

This video is either unavailable or not supported in this browser. (Error #4000)

In some other cases, people may also encounter "Media Resource not supported" or "Resource format not supported," both of which are almost identical to the original message when it comes to its meaning.

There are plenty of reasons why Twitch Error 4000 might show up while you're streaming. In most cases, the reason is the outdated or corrupted cached files stored on your local machine. Wrong DNS[ref en-2] settings and faulty graphic drivers may also be the reason for the problem arising. Sometimes, restarting the tab or the browser may fix the problem, although it is not the case for most users.

Method 3. Try alternative DNS

• Right-click on Start and pick Network Connections
• Under Advanced network settings, pick Change adapter options
• In the Network Connection window, right-click on your main connection (for example, Ethernet) and select Properties
• Select Internet Protocol Version 4 (TCP/IPv4) and click Properties below

  Preferred DNS server: 8.8.8.8
  Alternate DNS server: 8.8.8.9
• Press OK.

  

Method 4. Enable Hardware acceleration

Hardware acceleration can be used to play videos via your GPU instead of CPU, relieving the stress it endures. In some cases, people claimed that enabling the feature helped them fix Twitch Error 4000.

• On Chrome, go to Menu and pick Settings
• On the left side, select System
• Enable the Use hardware acceleration when available option on the right.

  

Method 5. Update your drivers

There are several ways how you can update drivers.

Method 6. Set your headset as a default audio device

• Right-click on the Speaker icon in your taskbar and select Sounds
• Go to the Playback tab
• Right-click on your headphones/speakers and select Set as Default Device.

  

Method 7. Try using the Twitch app or alternative browser instead

Also, Twitch has a dedicated application that you could launch directly from your computer and enjoy live streams with just a click of a button.
