Update the Hulu App

The error can occur due to bugs. So Hulu fixes the bugs and adds new features through app updates occasionally. You must update the app to the latest version to avail of these services. This may also fix the p-dev320 error.


  • Open the Google Play Store app on your device.

  • Find and tap on the Update button near the Hulu icon.


  • Open the Apple Store on your iPhone.

Go and relaunch the app once it is updated. In most cases, this would fix the problem.

Change the Device

If you are getting error code p-dev320 on Hulu, it may be due to your device only. Use Hulu on a different device to check for the error.

For example, if you’re using a mobile phone, open Hulu on a tablet or another device. In the case of smart TV, you can switch to a laptop. If the app runs properly on the alternate device, the issue is restricted to that device only, not a problem with the Hulu service.

To fix the problem with the primary Hulu device,

  • Close and relaunch all the apps on your phone, smart TV, Apple TV, Roku, or Xbox One.
  • Alternatively, restart your device.

This hopefully would resolve the issue related to Hulu streaming; else, try the following ways.

Reset Your Network Connection

If the error persists on all of your devices, then most probably, your network connection is behind the problem. If your internet connectivity is lost or slow, you may also get the error code p-dev320. To fix the connection issue, you can try these things:

  • Reset your router and reconnect the device to the network.
  • Remove/Forget the WiFi network on the device and reconnect to it again.
  • Check your internet connection speed. In case it’s too slow, contact the service provider or wait till it recovers the speed.
  • Unplug the MODEM from the power source and reconnect it. This will reset your MODEM & internet connection.

Perhaps, Hulu works perfectly, and the connection problem now doesn’t exist on your streaming device. If not, keep reading for another solution.

Clear Cache

Sometimes the corrupt data may also interrupt Hulu’s services. In that case, you need to delete the cache files. You can delete the Hulu app cache in the following steps:


  • On your phone, open Settings Apps.
  • Next, Tap on Hulu from the list.
  • Now open Storage.
  • Finally, tap on Clear Cache.


Since there is no particular way to clear cache memory in iPhone, thus alternatively, you can delete and then reinstall Hulu. This would clear the cache files in the app by default.

Check if Hulu is Down

Although it is less likely sometimes the Hulu server goes offline. This happens due to heavy app traffic or the server being under maintenance. Unfortunately, you cannot do much about it except wait until the services return online.

You can confirm on social media and Twitter if Hulu is down everywhere or only at your location. There you can also get the update when the server is back online.
