Hulu users sometimes experience streaming issues when trying to catch up to their favorite TV series, regardless of the device. For example, Hulu error code P-DEV320 is pretty common in the user community, and many have complained that it prevents them from accessing any Hulu content.

The error code is accompanied by a message that says We’re having trouble playing this. It may help if you turn your device off for a minute and then try again. As you can see, it’s not very helpful, so we’re here to help you fix this annoying issue with additional workarounds.

Steps to Fix Hulu Code P-DEV320

There are several ways in which you can approach the Hulu error code. We tried to list the following solutions in a logical order while taking into account Windows 10, Mac, Android, and iOS.

1. Restart your device

It’s right there in the error message. Try giving your desktop, laptop, smartphone, tablet, or Smart TV a reboot to see what happens. Log in with your Hulu credentials and try to watch content. If you no longer get error code P-DEV320, then it was likely a temporary glitch that you don’t really need to worry about.

2. Restart the Hulu app

If it’s not the device, perhaps it’s the Hulu app. You can restart it to give it a jolt and see if it got rid of that irritating error message. On Android, however, you should force stop the app before starting it back up again.

3. Restart your web browser

You might be using a web browser to try and watch Hulu on your Windows or Mac computer. However, since it’s susceptible to all sorts of errors, it’s a good idea to restart the browser app. Just make sure to close all processes first.

Remove your Hulu device, modem, and router from the power source if possible
Wait a few minutes and turn all of them back on

Then, take the results and put them up against the Hulu speed recommendations. If you’re below the minimum requirements, here are some things you can try to enhance your Internet quality:
