Can't play Hulu shows -- error P DEV320

Jump to solution

Hi All:

 

   I have an Ultra 4K stick. Sometime in the last week or so, whenever I try to play a Hulu show, I get a P DEV320 error a few seconds after the show starts.

   So far I've:

 

1) Deleted and reinstalled the Hulu app

2) Logged out and back into the Hulu app

3) Rebooted many, many times. Both with the on-screen reboot option, as well as by removing power for several minutes.

4) Made sure the Hulu app is up to date.

 

I can log into Hulu from my laptop and play shows without issue, so it's clearly not an account problem.

 

Any other suggestions for things I can try?

I got the P Dev320 error anytime I tried to watch The Great or any other Hulu original. Other TV shows and movies played fine but all Hulu originals threw up that error. I tried all the prescribed troubleshooting and none of it worked.

As weird as it sounds, what finally worked for me was going into Settings>Display Type and changing the display setting from "automatic", which included HDR10, and changing it to the setting that matched the resolution of my TV without HDR. Then, I restarted the Roku and went back into Hulu after the reboot. I don't know, maybe Hulu originals are incompatible with HDR or something but it worked and I've finally been able to watch season 3 of The Great.

I looked up the menu on a TCL Roku tv. It looks like if you select SETTINGS from the main menu, and then select TV PICTURE SETTINGS then that might put you in the right place. If there is an option for (may say) Automatic 1080p HDR10, UNSELECT that option and choose just 1080p TV or 720p TV. It would appear that the HDR (high dynamic range) is what's causing the issue. I pray this helps. 😊

Hello @mulveyr,

Welcome to your first post at the Roku community!

We understand that you're not able to play HULU on your Roku device and we thank you for doing the troubleshooting steps on your end. Error code P-DEV320 is a HULU error message and in order for you to resolve this issue, you need to clear the cache on the app.  We need to gather more information about this issue:

  • Is this the only channel that's having an issue?
  • Did you restart your Roku device before adding the channel back?

You can follow these steps below to make sure you're doing the right troubleshooting process:

  • Highlight the HULU app and press the * button on your remote to remove the channel
  • To clear the cache, restart your Roku device first before adding back the channel
  • Try to add back the HULU app and login to check if it's working

You'll want to check this article that will help you resolve this type of issue: How to resolve a channel playback issue

Let us know if the issue still persists!

Best regards,

Mel

Hello.

 

   The problem applies only to Hulu, I'm not having the issue with any other channels.

   As per your message, I:

   1) Logged out of the Hulu app

   2) Deleted the app from the Roku

   3) Rebooted the Roku

   4) Re-added the app, and logged in.

The same error reappears when I try, for example, to stream S3E1 of "The Great".

 

   Any additional suggestions?

Hello @mulveyr

Thanks for reaching out here in the Community!

If the problem with the channel persists even after removing and reinstalling it upon device restart, I suggest contacting the channel support directly to report the issue and request further assistance. Numerous channels on the Roku platform are created and managed by the channel providers themselves, making them the best resource to address the problem. If other channels are functioning properly and the issue occurs exclusively with that particular channel or app, it is likely that the problem originates within that specific channel. In such cases, the channel provider should investigate the issue to facilitate its resolution.

You can reach Hulu support here: https://help.hulu.com/s/?language=en_US

Karla

Yes! That was exactly it! I set mine to 1080 non-HDR, and it works fine now. Thank you!

Hopefully Roku support will add this to their knowledge base.

This solution worked like a charm. U was having the same issue with Hulu Originals and MAX originals as well. Changed my settings to 1080, and the movies finally play on both apps. Thanks, as this has been a for months now and none of the apps Technical Support were able to help. Roku needs to work on this!

Thank you for that tip.  I have been having that error message for months and have finally today scoured the internet to see anything but "turn off device, reset WiFi, Router, Roku, TV...your internet is too slow (I upgraded and still have the problem) and FINALLY you had the answer.  It finally works...Maybe HULU should hire you instead of all of those I spoke to who had no answers....Thanks again!!!

Unfortunately I don’t see that in my settings. Sounded like just what I needed too. I’m glad others were able to get their issue resolved. I have a TCL Roku tv so those options may not be available to me. 😞
