How to fix Twitch Error 4000?

Issue: 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.

Solved Answer

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.[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.

How to fix Twitch Error 4000?

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 In most cases, the reason is the outdated or corrupted cached files stored on your local machine.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[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.

If you want a quick and fast solution, we recommend using FortectMac Washing Machine X9 – this repair software is known for finding and replacing damaged system files automatically, clearing corrupted registries, cleaning cached browser files, and fixing malware[3] damage, and more.

Access geo-restricted video content with a VPN

Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
