If you rely on streaming services like Netflix and Hulu, you're probably no stranger to the occasional glitch. Unfortunately, the associated error messages are rarely helpful. Many users sometimes see Hulu error code p-dev320, for example. The name reveals nothing about the underlying problem, but in reality it is an indication that your Hulu app is having trouble communicating with the Hulu service. Here are the top seven ways to troubleshoot and solve this issue.

What is Hulu error code p-dev320?

While there can be a wide variety of issues which cause error code p-dev320 to occur, this error message indicates that the Hulu app on your device can't properly communicate with the Hulu service. It might be a network issue, a software problem on your device, or even a problem with the Hulu service or servers. Because the causes are varied, you might need to troubleshoot a variety of issues before you solve the problem.

Try Hulu on another device

When you have a problem as general as Hulu error code p-dev320, you probably want to narrow down where the issue is occurring — is it related to the specific device you're using, your internet connection, or is the problem at Hulu's end? An easy way to start to narrow that down is to see if you can reproduce the same error somewhere else. If you're getting error code p-dev320 on your Roku, for example, try watching the same video in Hulu on your phone or computer. Depending on whether the problem goes away on another device, you've learned a lot about where the problem is and where to focus your attention.

Close and restart your Hulu app

One of the first (and easiest) possibilities to consider is that your Hulu app is misbehaving. If the problem is temporary, you can force the app to close and then start it again. Here is how to close an app on Android and close an app on iOS. If you're trying to use the Hulu app on a smart TV or streaming player, close the app on that device — though the steps will vary depending upon what device you own.

Restart your device

If simply restarting the app didn't solve the problem, you can restart the entire device instead. This can resolve a host of issues related to software glitches and corrupted data in the device's memory. If you need a refresher, here's how to restart an iPhone, while you can turn off most Android devices by pressing and holding the power button for several seconds. Alternatively, you should be able to swipe down from the top of the screen to see a shortcuts panel, where you can find the power icon. For most other devices, like TVs and streaming players, unplug the device, wait a minute, and then plug it back in.

Update the Hulu app

It's possible you aren't using the most current version of the Hulu app, and your version has a bug or incompatibility that's keeping it from connecting properly with the Hulu service. Most devices update apps regularly without your intervention, but it's possible your Hulu app hasn't been updated recently. Here is how to update apps on your iPhone or on your Android phone. If you're using another device like a streaming device or TV, you may need to check your user guide to see how to update apps.

Clear the Hulu app's cache

If nothing else has resolved the problem so far, the problem might be related to the data cache used by the Hulu app. You can't easily clear this cache on some devices, but if you are using a phone or tablet, it's easy. On Android, the steps might vary depending upon which version of the operating system or which model phone you are running, but here's the general procedure:

1. Start the Settings app.

2. Tap Apps.

3. Go to the list of apps. You might need to tap See all apps. When you find it, tap Hulu.

4. Tap Storage & cache.

5. Tap Clear cache.

If you're using an iPhone, to clear the cache you will need to uninstall the app, which will delete the cache at the same time. Afterward, reinstall it from the App Store and sign back into your Hulu account.

Check your internet connection

Hulu error code p-dev320 is all about a lack of communication between the app and the Hulu service, so another important place to troubleshoot is your internet connection. First, check your wireless status at the top of the screen on your phone or tablet. You can also check for connectivity by using another app on your device that requires an internet connection, like another streaming service. Or open a web browser and run a Google speed test — if it fails to run or is very slow, that could be the culprit. If necessary, restart your modem and WiFi router by turning them off for at least two minutes, then plug them back in and wait for your internet connection to be restored.

See if there's a problem with Hulu

You might have a communication problem with Hulu because the service is offline, or there are serious connectivity issues with Hulu servers. This kind of glitch doesn't happen often, but it does happen. The easiest way to check is to go to Hulu's network status page at Downdetector, or just search for "Is Hulu down" in a Google search. If Hulu is offline, you need to wait and try again later.
