Do you keep encountering YouTube error 400? Although the platform strives to provide the best user experience, glitches still happen. I’ve experienced the same error a few times.

Luckily, it’s pretty easy to fix it. Below, I’ll explain what this error is, what causes it, and how to resolve it. Follow my step-by-step instructions and resume watching your favorite videos!

What Is Error 400 on YouTube?

Error 400 is a server problem that indicates your requests can’t be processed. Most importantly, it’s an error on the client’s end. Instead of loading the video, you’ll see this message instead: “There was a problem with the server [400].”

What Causes Error 400?

In my experience, here are the most common causes behind this error:

  • Internet issues: A stable connection is vital for consuming online content, especially for streaming videos.
  • YouTube server breakdown: YouTube’s servers could be experiencing issues. In this case, you can only wait it out.
  • Restricted mode in YouTube: Turning on restricted mode blocks mature or sensitive content from playing on your device. But sometimes, this setting can also trigger error 400.
  • Outdated software: Using an outdated web browser or an older version of YouTube can lead to problems like this.

The first thing you should do is ensure you’re connected to a stable and functional network. You should also reset your connection for good measure.
