What causes the “p-dev320” error on Hulu?

When you encounter the Hulu error code p-dev320, it is usually accompanied by a note explaining that the Hulu app on your streaming device can’t communicate with the Hulu service itself.

This can happen for a few reasons, which is why it’s such an annoying issue to deal with. You might be having a network problem or an issue with your device software. It may also simply be a problem on Hulu’s end with the streaming service itself.

Whatever the cause, the outcome on your end will be that Hulu won’t work. So, below are some ways to narrow down what’s wrong and fix the problem.

How to resolve Hulu error code p-dev320

Let’s start with the assumption that the issue is on your end rather than Hulu’s. There are a few quick tricks you can try to get back to streaming, depending on the specific issue. You can, admittedly, try these steps in any order. You may have a hunch about what’s wrong, so by all means, start there.

Try another device

It could be that Hulu error code p-dev320 is limited to the device you’re using rather than the app or your home network.

Try booting up Hulu on a different device to see if you’re still getting the error code. Those using a smart TV can switch over to your laptop, phone, or another device with Hulu installed. If you can stream without getting the error code, you’ve likely just narrowed down the problem to a single device.

If the issue is just the one device. Try restarting it to see if the problem is resolved. That’s often the quickest and simplest fix, and you might as well not waste time and energy until you’ve given it a try.

If you can stream after the restart, great. If not, give one of these other options a try.

Restart the Hulu app

This is the quickest and easiest solution. In the case the Hulu app itself is acting up, just shut it down and reopen it. If you’re using a smart TV, just go back to your home menu and reopen Hulu.

If you’re using an Android or iOS device, follow the steps on your specific device.

How to close an app on Android:

  1. Launch the Settings app.
  2. Go into Apps.
  3. Tap on See all apps.
  4. Find and select Hulu.
  5. Select Force stop.
  6. Confirm by hitting OK.

How to close an app on iPhone:

  1. Slide your finger up from the bottom, then hold for a bit.
  2. The app switcher will show up. Find Hulu.
  3. Swipe the Hulu app up, away from the screen.

Once Hulu is closed, go ahead and reopen it and see if the problem is solved.

Update your Hulu app

Your device likely updates the Hulu app automatically, but if it doesn’t, it could be that your version of the app is out of date and something is interfering with its ability to connect to the service. If that’s the case, you’ll want to go into your settings and give it a quick update.

How to update the Hulu app on Android:

  1. Launch the Google Play Store.
  2. Tap on your profile icon in the top-right corner.
  3. Select Manage apps & device.
  4. Tap on Updates available.
  5. Look for Hulu and hit the Update button next to it. Alternatively, you can select Update all to update all your apps in one go.

How to update the Hulu app on iPhone:

  1. Launch the Apple App Store.
  2. Tap your profile icon in the top corner.
  3. Scroll down to the list of apps until you see Hulu.
  4. Select Update if it’s available. You can also hit Update All to update all apps in one sweep.

Clear your cache

If you’re still trying to solve a Hulu error code p-dev320 on a single device, you may need to declutter your app.

The Hulu app’s cache might be what’s interfering with the service if you haven’t cleared it in a while. This process will vary depending on your device.

How to clear cache on an Android app:

  1. Launch the Settings app.
  2. Go into Apps.
  3. Tap on See all apps.
  4. Find and select Hulu.
  5. Select Storage & cache.
  6. Tap on Clear cache. You can also tap on Clear storage to delete all app data.

With an iOS device, you can’t clear the cache, but you can simply uninstall the app and reinstall it, which will clear the cache automatically.

How to delete an iPhone app:

  1. Find the Hulu app. Tap and hold onto it.
  2. Select Remove App.
  3. Tap on Delete App.
  4. Go to the Apple App Store and reinstall Hulu.

Reset your internet

If you’re still experiencing the same problem, or if the problem applies to multiple devices, you’ll want to see if you might simply have an internet connection problem.

You won’t always notice if your internet speed is too low, though it may be that you’re already dealing with sluggish connectivity. In either case, you can try rebooting your home internet.

Just turn off or unplug your home modem and router. Leave them off for a minute or so, then plug them back in. You may need to contact your internet service provider if you’re still not getting enough speed.

Check if Hulu is down

The last and least helpful possibility is that Hulu is down. Least helpful because there’s really not much you can do. You’ll just have to wait for the service to come back online.

There’s nothing to do on your end in this scenario, because the problem simply isn’t on your end.

You can track that on sites like Downdetector. There, you can see whether the service is experiencing outages and stay aware so you can see when it’s back up.
