How to Fix the Hulu Error Code P-DEV320

To fix this error code, follow these troubleshooting steps in order. If Hulu still doesn't work by the time you get to the end, the problem is probably something that Hulu will have to fix. You can contact Hulu customer service for additional information, but they are probably already working on a fix.

  1. Try Hulu on a different device. If you have more than one device that's capable of playing Hulu, then try it on a different one. For example, check to see if it works on your phone if you were watching it on your computer, or try it on your Xbox One if you were watching it on your Nintendo Switch.

    If Hulu works on your other devices, then suspect a problem with the first device, such as an internet connectivity problem or outdated app.

  2. Make sure your Hulu app is up to date. If your Hulu app is outdated, it can cause error code p-dev320, which is especially likely to be the problem if Hulu works on some of your devices and not others.

    Check out this helpful Hulu resource for Hulu app release notes. Choose your platform from the list to find out the numbering of the latest version of the Hulu app for your device. If the version of your app is lower than the number of the newest version, yours is outdated.

  3. Clear your Hulu app cache and data. If your Hulu app is already up to date, then it may have some corrupt data. In that case, clearing the Hulu app cache and local data may fix the problem.

    • On Android: Go to Settings > Apps > See all apps > Storage and cache > clear storage, then clear cache.
    • On iOS: Go to Settings > General > Storage > Hulu, then delete and uninstall the app. Reinstall it via the app store.
    • On Fire TV: Go to Settings > Applications > Manage Installed Applications > Hulu > Clear cache > Clear data.

    If you're using the Hulu web player, you should clear your browser cache and data, so if anything there is causing issues, it's cleared out.

  4. Check other streaming services. Using the same device that is suffering from the p-dev320 error, try other streaming services like Netflix. If another service also fails to work and generates error codes, that's evidence that your device has a connectivity problem. You might need to update your device, restart it, or fix its connection to the internet.

  5. Try Hulu on a different internet connection, such as a mobile internet connection. If Hulu works on one internet connection but not the other, you have a connectivity problem with the primary internet connection.

  6. Check your internet connection. See if other streaming apps work on your device if you have any. If your device is having connectivity problems, that can cause this error code.

  7. Check your internet speed. Do this with the device you're trying to use with Hulu, which has various internet speed recommendations. If it doesn't have the required rate, that could cause the issue. Contact your internet service provider to see how fast your connection is supposed to be.

  8. Restart your device and your local network hardware. You can sometimes resolve connectivity issues by restarting your device and network hardware.

  9. Check to see if Hulu is experiencing an outage. The service might be down for everyone.

If Hulu still doesn't work after following all of the previous steps, consider contacting Hulu to let them know about the problem and to inquire about further assistance.
