How to Fix the Hulu Error Code P-DEV320

Follow the below given steps in the given order. If Hulu still doesn’t work after trying all the steps, the issue likely requires the assistance of Hulu’s Customer support.

If Hulu is not working on one device, try accessing it on a different device. For example, use a computer if you were on a mobile device, or a mobile device if you were on a smart TV.  If the app functions well on the other device, there may be a problem with the previous  device you were using instead of Hulu.

If Hulu functions properly on the other device you have connected to, this means that the previous device may have an outdated software version or internet connectivity issues.

Close the app fully and open it again:

Restart the app if it’s frozen or not responding. 

Use the instructions for your particular device if you’re using an iOS or Android smartphone.

How to close an app:

  • Step 1: Open your Settings on your Android Device.
  • Step 2: Tap on the Apps & select “See All Apps”
  • Step 3: Here you will find Hulu & tap.
  • Step 4: Once you click on Hulu, now you have to Select “Force stop”.
  • Step 5: Confirm by hitting OK.

Check your internet speed:

Use Downdetector to see if there are any problems with Hulu. A graph of the reported outages over the previous 24 hours will be displayed. If the number of reports suddenly increases, there probably is a problem with Hulu. You’ll have to wait till the app fixes such a bug.
