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 original device. It may have an internet connectivity problem or the Hulu app may be outdated.

  2. Make sure your Hulu app is up to date. If your Hulu app is outdated, it can cause error code p-dev320. Update your app if it's outdated. This is especially likely to be the problem if Hulu works on some of your devices and not others. In some cases, you may have to delete the app on Android or remove it on iOS, then reinstall it to force an update.

    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 If the version of your app is lower than the number of the latest version, yours is outdated.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 bad or 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 the your browser cache and data so if anything there is causing issues it's cleared out.

    Some devices require you to uninstall an app to clear its cache.

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

  5. Try Hulu on a different internet connection. Do you have a cellular internet connection in addition to your home connection? Streaming Hulu using your cellular data can get expensive, but checking to see if Hulu works on a different internet connection can be useful.

    If Hulu works on one internet connection but not the other, you have a connectivity problem with the original 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 speed, that may be 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. Connectivity issues can sometimes be resolved by simply restarting your device and network hardware. To accomplish this, you'll need to fully shut down your router and modem, unplug each one from the wall, and wait a while before plugging everything back in.

  9. Check social media. At this point, it's starting to look like the problem might not be on your end. Check potentially useful Twitter hashtags like #hulu down, and make sure to select the latest tab. If there Hulu is experiencing an outage, people will be talking about it.
