How to Fix Hulu Error Code P-DEV320?

To resolve Hulu code P-DEV320, follow these troubleshooting solutions in sequence. If Hulu still doesn't function at the conclusion of this guide, the issue is likely something that Hulu has to solve. You may contact Hulu Customer Service for further information, however, they are likely already working on a solution.

Test Hulu on a Different Device


Hulu error P-DEV320 is somewhat generic, so you may want to determine if the issue is on your end (due to the equipment you're using) or Hulu's (due to your internet connection) before attempting to fix it.

One simple technique to restrict the possibilities is to try to replicate the problem in another setting. You may view the same Hulu episode on your phone or computer if you're receiving the P-DEV320 issue on your Roku. If the issue disappears on a different device, you know exactly where to go for a solution.

Restart Your Hulu App

One of the simplest and most obvious reasons is that your Hulu app is malfunctioning. If the issue is transitory, you may force the application to shut down and then relaunch it. Here are the steps to end an Android app and an iOS app.

For Android: 

  • Swipe up from the bottom, then hold and release.
  • Swipe up on the Hulu app.

For iOS:  

  • Swipe up from the bottom of the Home Screen and pause in the center of the screen.
  • Swipe to the right or left to locate the Hulu app.
  • Swipe up on the preview of the Hulu app to end it.

If you're attempting to use the Hulu app on a smart TV or streaming player, you'll need to shut the app on that device; the specific procedures may differ depending on the device you possess.

Update the Hulu App


It is likely that you are not using the most recent version of the Hulu app and that a bug or incompatibility is preventing the app from connecting to the Hulu service. It's conceivable your Hulu app hasn't been updated lately, despite the fact that most devices update applications automatically. 

Here is how to update applications on your iPhone or Android device.

For Android: 

  • Open the Google Play Store app.
  • Tap the profile icon at the top right.
  • Tap Manage apps & device. Apps with an update available are labeled Update available.
  • Tap Update.

For iOS:  

  • Open the App Store.
  • Tap your profile icon at the top of the screen.
  • Scroll to see pending updates and release notes.
  • Tap Update next to the Hulu app to update Hulu only, or tap Update All.

If you're using a different device, such as a streaming device or television, you may need to consult the user manual to learn how to update applications.

Clear Your Cache and Data

Hulu clear cache

If nothing else has remedied the issue, it may be due to the data cache utilized by the Hulu application. With certain devices, it is difficult to clear the cache, but on a smartphone or tablet, it is simple.

The procedures may differ based on the operating system version or phone type you are using, but here is the basic procedure:

  • For Android: Go to Settings > Apps > See all apps > Storage and cache > clear storage, then clear cache.
  • For iOS: Go to Settings > General > Storage > Hulu, then delete and uninstall the app. Reinstall it via the app store.

If you're using the Hulu web player, you should clear your browser's cache and data. This will ensure that any problematic data is removed.

Check Your Internet Connection

Hulu error code P-DEV320 is caused by a lack of communication between the Hulu app and the Hulu service; thus, your internet connection is another crucial troubleshooting step.

Check the wireless signal strength at the top of the screen on your smartphone or tablet.

You may also test connectivity by launching another app that needs an internet connection, such as a different streaming service, on your smartphone.

Or, open a web browser and do a Google speed test; if it fails to load or is very sluggish, this may be the cause.

If required, unplug your modem and WiFi router for a minimum of two minutes, then reconnect them and wait for your internet connection to be restored.

Check Hulu's Status

You may be unable to communicate with Hulu because the service is unavailable or because Hulu servers are experiencing severe connection difficulties. This kind of error seldom occurs, although it does occur. The simplest method is to visit Hulu's network status page on Downdetector or do a Google search for is Hulu down? If Hulu is unavailable, you must wait and try again at a later time.

Contact Hulu Customer Service

If Hulu still does not function after completing the above steps, try contacting Hulu to report the issue and request more help.
