How to Fix Hulu Error Code P-DEV320

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 listed the following solutions in a logical order and updated them to reflect current Hulu guidance and modern devices (Windows 10/11, macOS, Android, iOS, Roku, Fire TV, and smart TVs).

1. Check for Hulu service issues or outages

Before you dive into fixes, confirm it’s not a platform-side problem. Check Hulu’s help articles & tips or Hulu’s social channels. If others are seeing P-DEV320 (and related codes like P-DEV318/P-DEV322), it may clear up once Hulu resolves the issue.

2. Restart your device

It’s right there in the error message. Try giving your desktop, laptop, smartphone, tablet, streaming stick, 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, it was likely a temporary glitch.

3. Restart the Hulu app

• Use a wired Ethernet connection if possible
• Try a different network (mobile hotspot vs. home Wi-Fi) to isolate the issue

12. Customize your DNS servers

2. Go to Update & Security
3. Open Troubleshoot > Additional troubleshooters > Internet Connections > Run the troubleshooter
4. Restart your PC

15. Disable your VPN or proxy server

Most VPNs/proxies aren’t reliable with Hulu and can cause authorization/connection errors (including P-DEV320). Turn them off and test again. If you need a VPN for privacy, connect to your home region and avoid free/slow services.

16. Check for system updates

Keep your OS, TV firmware, and streaming devices updated to the latest version for best compatibility with current Hulu apps and DRM components.

Extra tips (device & account specifics)

• Supported devices/OS: Verify your device is on Hulu’s current supported list and OS version (see Hulu supported devices).
• Hulu + Live TV Home network: If Live TV works on one device but not another at home, recheck your designated home network settings (see Manage Home Network).
• Try another profile/device: If the error only affects one profile or device, it’s likely app data or device-specific.
• Related codes: P-DEV318 and P-DEV322 are closely related connection/authorization errors and usually respond to the same fixes above.

Hulu streaming issues: CONCLUSION

To recap, Hulu error code P-DEV320 is a streaming problem that can occur on the server or client side. It often resolves on its own, but if it doesn’t, work through the steps above: restart devices/apps/browsers, power cycle your network, manage paired devices, clear app/browser cache, update the Hulu app and system software, check your internet speed against Hulu’s speed recommendations, adjust DNS, run troubleshooters, and temporarily disable VPNs/proxies.
