In this guide, we will show you how to fix the P-DEV320 error on Hulu that prevents you from watching your favorite movies and TV shows. 

1. Check Hulu’s Servers.

If the servers are down, the best thing to do is wait until Hulu addresses the issue on their end. 

However, you can still try the remaining methods below and see if anything works out for you. 

2. Try Using A Different Device. 

If you own another device capable of running Hulu, we suggest that you try using the platform on that device. This way, you can check if the problem is with the platform or the device you are using.

If Hulu is working on other devices, you may be dealing with network connectivity issues or outdated versions of the app. 

3. Try Playing Another Show.

Some movies and TV shows on Hulu may encounter temporary bugs and become unavailable for a certain period. If the P-DEV320 error on Hulu occurs when playing your favorite shows, go back to the media library and select another title. 

If other shows on the platform play without any issues, the problem is isolated to that specific movie or TV show. Go to the last method below to call the attention of Hulu’s support team. 

4. Change the Playback Quality. 

Playback issues on Hulu could also be related to network connectivity issues. If your network is not fast enough to load a specific show, you may experience error messages and other issues on the platform.

  1. First, access the Hulu app on your device and tap on your Profile
  2. Next, tap on the Settings tab and select Cellular Data Usage
  3. Lastly, change the option to Save Data and close the Settings page.

Speed Test

Restart your router if the result indicates that your connection is unstable. Unplug the power cable of your router for at least 10 seconds before reconnecting it.

Once done, run another test on your network to confirm if restarting your router fixed the problem. Contact your ISP and ask them to improve their service if you continue to experience network-related issues. 

Hulu also requires a minimum internet speed of 3 Mbps to enjoy its services without issues. If your current plan is below that speed, consider upgrading your subscription to avoid other problems in the future.
