Hulu Error Code: P-DEV320.” This generic but persistent error can bring your streaming night to a screeching halt, leaving you wondering what went wrong and how to fix it.

The good news is that error code p-dev320, along with its close relatives p-dev318 and p-dev322, is one of the most common issues Hulu users face. While it can appear on any device—from your smart TV to your smartphone—it’s almost always fixable. The error points to a communication breakdown between your device and Hulu’s servers, but the cause can range from a weak internet connection to a simple software glitch.

This comprehensive guide will walk you through everything you need to know to solve Hulu error code p-dev320 for good. We’ll explore what the error means, uncover its common causes, and provide detailed, step-by-step solutions for every device. By the end, you’ll be equipped to troubleshoot this issue and get back to seamless streaming.

What is Hulu Error Code P-DEV320?

At its core, Hulu error code p-dev320 signifies a playback failure. Your device, whether it’s a Roku, Fire Stick, gaming console, or computer browser, is failing to maintain a stable line of communication with Hulu’s servers. This interruption prevents the video content from loading and playing correctly.

The “p-dev” part of the code refers to a “playback device” error, which means the problem lies somewhere in the chain of command between your hardware and Hulu’s content delivery network. It’s a general-purpose error, which is why the solutions involve checking several potential weak points in that chain.

You might also encounter similar codes like:

• P-DEV318: This error is often linked to the same connectivity issues as p-dev320.
• P-DEV322: Like its counterparts, this code usually points to a network or server communication problem.

The troubleshooting steps for all three are nearly identical, so the solutions in this guide will help you tackle any of them.

Common Causes of Hulu Error Code P-DEV320

Before diving into the fixes, it’s helpful to understand what might be causing the problem. Identifying the root cause can help you resolve the issue faster and prevent it from happening again.

1. Poor Internet Connectivity: This is the number one culprit. An unstable, slow, or inconsistent Wi-Fi signal can disrupt the data stream from Hulu’s servers. Streaming requires a constant flow of information, and any hiccup can trigger the error.
2. Outdated Hulu App: An old version of the Hulu app may contain bugs or compatibility issues that have been resolved in a newer update. Running an outdated app is a common cause of playback errors.
3. Corrupted Cache or Data: Your device stores temporary files (cache) to help apps load faster. Over time, this data can become corrupted, leading to glitches and errors like p-dev320.
4. Hulu Server Issues: Sometimes, the problem isn’t on your end at all. Hulu’s servers can experience outages or high traffic, especially during major live events or premieres, which can affect service for everyone.
5. Device-Specific Glitches: A temporary bug within your streaming device (smart TV, gaming console, etc.) or web browser can interfere with the Hulu app’s performance.
6. VPN or Proxy Interference: While VPNs are great for privacy, they can sometimes interfere with streaming services. Hulu’s platform may detect and block VPN traffic, resulting in a playback error.

9 Proven Methods to Fix Hulu Error Code P-DEV320

Now, let’s get to the solutions. Work through these steps in order, as they start with the simplest and most common fixes before moving to more involved troubleshooting.

Method 1: Perform a Hard Restart of Your Device and App

The oldest trick in the tech support book often works for a reason. A full power cycle can clear out temporary glitches and re-establish a fresh connection.

1. Close the Hulu App Completely: Don’t just return to the home screen. Make sure the app is fully closed.
2. • On mobile (iOS/Android): Swipe up from the bottom of the screen to open the app switcher, then swipe the Hulu app away.
   • On a streaming device (Roku, Fire TV): Go to your device’s settings, find the “Applications” or “Apps” menu, select Hulu, and choose “Force Stop” or “Close.”
   • On a web browser: Close the browser tab or the entire browser window.
2. Power Down Your Streaming Device:
3. • Unplug your smart TV, Roku, Fire Stick, or gaming console directly from the power outlet.
   • Wait for at least 60 seconds. This allows the internal components to fully discharge and reset.
3. Restart Your Network Hardware:
4. • While your device is off, unplug your modem and router from the power source.
   • Wait another 60 seconds.
   • Plug the modem back in first and wait for its lights to stabilize (usually about 1-2 minutes).
   • Then, plug the router back in and wait for its lights to become solid.
4. Power Everything Back On: Plug your streaming device back in, turn it on, and relaunch the Hulu app. Try playing the video again.

This simple process resolves a surprising number of streaming issues by clearing out temporary system and network conflicts.

Method 2: Check Your Internet Connection Speed

Hulu has minimum speed requirements for smooth playback. If your connection is too slow, you’ll run into buffering and errors like p-dev320.

• Standard Definition (SD): 3.0 Mbps
• High Definition (HD 720p/1080p): 6.0-8.0 Mbps
• 4K Ultra HD: 16.0 Mbps
• Hulu + Live TV: 8.0 Mbps or higher

Run a speed test on the device you’re using to watch Hulu. You can use a website like Speedtest.net or Fast.com. If your speed is below the recommended minimum, this is likely your problem. Try moving your router closer to your streaming device or switching to a wired Ethernet connection if possible.

Method 3: Update the Hulu App

Developers regularly release updates to fix bugs and improve performance. An outdated app is a frequent cause of playback errors.

• On Roku: Go to the home screen, highlight the Hulu app, press the * button on your remote, and select “Check for updates.”
• On Amazon Fire TV/Stick: Navigate to Settings > Applications > Manage Installed Applications. Select Hulu and check for an update option.
• On Android: Open the Google Play Store, tap your profile icon, and go to Manage apps & device. Find Hulu in the “Updates available” list.
• On iOS (iPhone/iPad): Open the App Store, tap your profile icon, and scroll down to see pending updates.
• On Smart TVs (Samsung, LG, etc.): Go to your TV’s app store, search for Hulu, and see if an “Update” button is available.

Method 4: Clear the Hulu App’s Cache and Data

Corrupted temporary files can cause the Hulu app to misbehave. Clearing the cache forces the app to download fresh data, which can resolve the p-dev320 error.

• On Amazon Fire TV/Stick: Go to Settings > Applications > Manage Installed Applications > Hulu. Select Clear Cache, and then Clear Data.
• On Android: Go to Settings > Apps > Hulu > Storage & cache. Tap Clear Cache, then Clear Storage.
• On Roku: Roku doesn’t allow clearing the cache for individual apps. The best way to do it is to uninstall and reinstall the app. Highlight Hulu, press *, select Remove channel, then go to the Channel Store to add it back.
• On iOS: Similar to Roku, you can’t clear the cache directly. You must delete the app (Settings > General > iPhone Storage > Hulu > Delete App) and reinstall it from the App Store.
• On Web Browsers: If you’re watching on a computer, clear your browser’s cache and cookies. This is usually found in the Settings or History menu under “Clear browsing data.”

Method 5: Check if Hulu Is Down

Sometimes the problem isn’t you—it’s Hulu. If their servers are experiencing an outage, you won’t be able to stream no matter what you do.

• Use a Downdetector Website: Visit a site like Downdetector.com or IsItDownRightNow.com and search for Hulu. These sites track user-reported outages. If you see a large spike in reports, it indicates a widespread problem.
• Check Hulu’s Social Media: Hulu’s official support accounts on platforms like X (formerly Twitter) often post updates during major outages.

If Hulu is down, the only solution is to wait for their engineers to fix it.

Method 6: Try a Different Device

To determine if the issue is with a specific device, try watching Hulu on another one. For example, if you’re getting the error on your smart TV, open the Hulu app on your phone or laptop.

If Hulu works on the other device, it confirms the problem lies with the original device or its connection. If the error appears on all your devices, it points to a network-wide issue or a problem with your Hulu account.

Method 7: Switch to a Wired Connection

Wi-Fi is convenient, but it’s prone to interference and signal drops. A wired Ethernet connection provides a more stable and faster link to the internet, which is ideal for streaming.

If your streaming device (like a smart TV, gaming console, or streaming box) has an Ethernet port, try connecting it directly to your router with an Ethernet cable. This simple change can often eliminate connection-related errors for good.

Method 8: Disable Your VPN

If you are using a Virtual Private Network (VPN) or proxy service, it could be the source of your problem. Streaming services like Hulu actively work to block VPN traffic to enforce regional content restrictions.

Try disabling your VPN and then relaunching Hulu. If the error disappears, your VPN was the cause. Some VPNs offer dedicated servers for streaming that may work with Hulu, but this is not guaranteed.

Method 9: Contact Hulu Support

If you have tried all the steps above and are still seeing error code p-dev320, it’s time to contact the experts. There may be a more complex issue with your account or a known problem they can help with.

You can reach Hulu’s customer support through their Help Center website, which offers chat and phone support options. Be sure to tell them the error code you’re receiving and the troubleshooting steps you’ve already taken.
