 Key Points

  • The error is most frequently encountered when you are streaming through a browser.
  • You can fix this error by refreshing your browser in various ways.
  • There isn’t much you can do if the issue is on Hulu’s end other than being patient.

NOTE: First and foremost, implement these fixes:

  1. Checking your internet speed.
  2. Restarting your router.

1. Try Using A Different Device

The likelihood that your particular device brought on the error is the highest. Therefore, the first thing I advise you to do is check it out on another device capable of playing Hulu to see if it works there. For example, if you get an error code on your computer, check if it functions on your Xbox One.

In doing so, if the problem resolves and the app is functional once again, it may be safe to assume that the issue was with the device you previously used. However, if it isn’t resolved, you must direct your attention elsewhere. 

When I faced this error, it was on my Xbox One, and I could fix it by logging onto the account on my computer.

2. Troubleshooting The Browser

As mentioned above, I tested the error to be mostly on the browser version of Hulu. As such, I could fix it by clearing the browser cache. Furthermore, I tested that even switching to a different browser could fix it.

3. Clear Hulu Data And Cache 

This is another way that I’ve fixed this error, as well as similar errors on Hulu. In fact, our team tested that this is one of the most effective fixes for the error.

This is because, often, to improve application speed, apps save unnecessary data on your devices. However, the data is frequently corrupted, which causes streaming issues. Therefore, clearing the cache data can be of some help, as was the case with users on Reddit.

Following are the ways you can do this:

If Hulu itself caused the error, they will presumably update their forum to let folks know about this unprecedented event. As such, I greatly recommend doing this. If nothing else works, the Hulu forums and social media profiles to determine if there is a breakdown or outage. If so, wait for the issue to be resolved from their end.

5. Contact Customer Support

If the error is not resolved even after trying all the tips and tricks mentioned above, the last resort is to contact customer service. Log in to visit their contact page. Report the issue you are facing and ask for additional help. I hope doing this can finally fix the issue, even if nothing else works.

The Verdict

Researching for this error astounded me with how different the different kinds of browsers are from each other. The issue is more prevalent in some than in others, but the companies are constantly releasing updates to defend against problems like this.

Hopefully, in the future, you won’t have to face errors just because you’re using your favorite browser.
