Hulu is one of the most popular streaming services, but nothing is more frustrating than sitting down to watch a show only to be stopped by an error code. Error P-DEV320 is one of the most common problems Hulu users run into. It blocks playback, interrupts movies or live TV, and can show up on almost any device.
This guide will explain what the error means, what causes it, how to fix it, and how to prevent it from coming back.
What Does the Hulu P-DEV320 Error Code Mean?
Hulu error code P-DEV320 is a playback error. It means the Hulu app or device is having trouble communicating with Hulu’s servers. In plain terms, something is stopping Hulu from loading video content correctly.
You’ll usually see this error on the screen with a message like “We’re having trouble playing this. Hulu Error Code: P-DEV320.” It shows up on Smart TVs, Roku, Fire TV Stick, iOS and Android apps, and even web browsers.
This code belongs to Hulu’s “P-DEV” family of errors, all related to communication issues, but P-DEV320 is the one users report most often.
Common Causes of Error P-DEV320
Some of the main reasons this error shows up include:
- Outdated Hulu app version
- Corrupted cache or app data
- Weak or unstable internet connection
- Hulu server outage or maintenance
- Device compatibility issues
- VPN or proxy interfering with Hulu
How to Fix Hulu Error Code P-DEV320
The proper fix depends on whether the issue is with your app, device, or internet. Try these one by one until Hulu works again.
Fix #1: Restart App and Device
A restart is one of the quickest ways to clear out minor glitches that cause Hulu to freeze or show errors. Instead of just minimizing the app, close Hulu completely and then restart your device, whether it’s a phone, Smart TV, Roku, Firestick, or console.
Once the device powers back on, open Hulu again and try to stream. This simple reset often clears temporary errors without any other steps, making it the first fix you should try.
Fix #2: Update Hulu App
If you’re running an old app version, Hulu may not connect properly. Updating is easy and often fixes playback errors. Open your device’s app store, search for Hulu, and check if an update is available. Install it, then relaunch the app.
Fix #3: Clear Cache and Data
Old or corrupted files inside the app can cause errors. Clearing them gives Hulu a fresh start.
On Android:
- Go to Settings > Apps > Hulu.
- Select Storage.
- Tap Clear Cache and then Clear Data.
On iOS, the only option is to delete the app and reinstall it. That clears all cached files automatically.
Fix #4: Check Internet Connection
Many times, the error has nothing to do with the Hulu app but with your internet. Hulu needs a steady line to its servers, so start by restarting your router and modem to refresh the connection.
After that, run a quick speed test to confirm you meet Hulu’s requirements, since slow speeds can trigger playback errors.
If Wi-Fi is weak, try moving closer to the router or switch to a wired connection for better stability. And if your internet keeps dropping often, the safest step is to call your provider for support.
Fix #5: Disable VPN or Proxy
Hulu often blocks VPNs and proxies because of licensing rules. If you’re using one, turn it off and try streaming again. A standard connection usually clears the error.
Fix #6: Reinstall the Hulu App
If nothing has worked so far, do a clean reinstall.
Here are the steps you can follow:
- Delete the Hulu app from your device.
- Restart the device to clear background files.
- Reinstall Hulu from the app store.
- Log in again and test playback.
This fix replaces corrupted files that clearing cache may not solve.
Fix #7: Contact Hulu Support
If the problem keeps coming back, it may be on Hulu’s side or linked to your account. At this point, reach out to Hulu Support through the Help Center or live chat. Provide details about your device, the error code, and what fixes you’ve already tried.
Tips for Prevention to Avoid Future Errors
To avoid seeing P-DEV320 again, here are some quick habits:
- Keep your Hulu app updated to the latest version.
- Restart your router once a week for a fresh connection.
- Avoid streaming on Hulu while downloading large files.
- Don’t use VPNs or proxies with Hulu.
- Clear cache and app data regularly.
- Replace old streaming devices that no longer get updates.
