Error code P-DEV320 appears to be a very common error with the well-known on-demand video streaming service Hulu. It was reported for the first time about a year ago.

The error code appears on most devices, whether we’re talking about smart TVs, mobile devices, Xbox One, or Roku. The cause is, in most cases, either network-related or app-related. Additionally, the developer admitted from the beginning that sometimes the issue can also be on their side.

Hulu announced in the community that they are working on a fix, but there has been no official clear solution. On the contrary, basic troubleshooting is recommended in most cases.


How to fix the P-DEV320 error code after all?

1. Ensure that the Hulu app and your device are updated

Many problems are caused by outdated apps. So check for available updates in the apps store or your device’s settings menu.


2. Clear cookies and cachefix P-DEV320 error

On devices running on Windows, Android, or iOS, cached data is usually found in the storage/privacy section of the Settings menu.

On Apple TV you need to uninstall and reinstall the app to clear cache and data.

For Xbox One see the following steps:

  1. Go to Menu.
  2. Choose My Games and Apps > Apps.
  3. Highlight the Hulu.
  4. Hit Menu on your controller.
  5. Tap on the Manage Apps > Clear saved data.

Also, for Roku:

  1. Select Home on the main menu.
  2. Then, on the remote controller press Home 5 times + press Up + press Rewind 2 times + press Fast Forward 2 times.
  3. It should take a few seconds to clear the cache.

Clearing the cached data help to make some space on your device by removing temporary files and improving streaming conditions, as well as getting rid of possible corrupted files that got randomly installed.


3. Whitelist an ad domain

You might have completely blocked ads coming from Hulu by blocking the ads-e-darwin.hulustream.com domain. You have to whitelist it back on the proxy authentication server and it will most likely fix the issue.


4. Check your Internet connectivity

  1. Turn off all devices connected to your home network.
  2. Close all background apps or other programs.
  3. Then, connect your device to the router using an Ethernet cable.
  4. Also, place the modem or router near your device.

Be aware that to fully enjoy your video streaming experience, Hulu requires the following Internet speeds:

  • 3.0 Mbps for the Hulu streaming library
  • 8.0 Mbps for live streams
  • 16.0 Mbps for 4K content

Streaming with lower speed is also possible, which will reduce the video quality.


5. Deactivate your device

In your Hulu your account page, remove your device by logging out completely. Then, log back in by re-entering your credentials. Try to launch Hulu again and see if the problem is solved.


6. Perform a power cycle
