Hulu is a popular app for streaming videos but, like any other, it is susceptible to the occasional “Error Code: p-dev320” when you are trying to stream something.
This error can occur when you are attempting to watch TV shows or movies, or using Hulu with Live TV to stream a live event.
This error message will look like this:
“We’re having trouble playing this. It may help if you turn your device off for a minute and try again. Hulu Error Code: P-DEV320“
You might also see error code P-TS207 or P-DEV322. Any of these errors can happen on any device which can run the Hulu app, and that includes your browser’s web player.
These errors are typically caused by network or connection issues, although playback failures can happen when the app is outdated or the Hulu service has a glitch.
Causes of Hulu Error Code P-DEV320
This error happens when there is a problem with the main Hulu servers’ communication with your Hulu web player or app.
It can happen when there are connectivity issues with your network, problems at Hulu’s end, or by trying to use an outdated Hulu app.
Error codes P-TS207 and P-DEV322 are similar but caused by issues at Hulu’s end which they need to fix.
How to Troubleshoot Hulu Error Code P-DEV320

You can also got the error code on your Nintendo Switch, see whether it will play on your phone or tablet. If it works on another device, then the issue is probably on the first device, and could be an outdated app or internet connectivity issue.
Solution #2: Make Sure Hulu is Up to Date

Take a look at this Hulu resource for app release notes. You can look at your platform to find out which version you should be running.
If the version on your device has a lower number, you need to update it.
Solution #3: Clear Hulu Data and Cache
It is possible that you have some corrupt data somewhere. Clearing out the Hulu app local data and cache might help in that instance.
This is how to clear them out:
Clear Hulu Data and Cache On iOS:
- Navigate to “Settings“.
- Go to “General” than to “Storage“.
- Select “Hulu” and “Uninstall Hulu“.
- Reinstall Hulu using the App Store.
Clear Hulu Data and Cache On Android:
- Navigate to “Settings“, than to “Apps“.
- Click on “See All Apps” and on “Storage and Cache“.
- Select “Clear Storage” and “Clear Cache“.
Clear Hulu Data and Cache On Fire TV:

- Select “Manage Installed Applications” and select “Hulu“.
- Click on “Clear Cache” and “Clear Data“.
If you are using the web player version of Hulu then clear your data and browser cache to make sure you clear out anything that might be causing the Hulu playback error.
Solution #4: Check Whether Other Streaming Services Work
Try another streaming service, like Prime or Netflix, on the same device giving you the P-DEV320 error.
If that won’t work either, it means your device has a connection issue. You might need to update or restart your device or check the internet connection.
Try Hulu using a different connection, for example your mobile connection. If it works on that that means something is wrong with your main internet connection.
Check the internet speed with the device you got the error code on to see whether it is good enough for streaming.
You could contact your ISP to find out the speed it is supposed to be. Also check whether Hulu has an outage.
Conclusion
If none of the above works, the next step is to contact Hulu and tell them about the issue (“Error Code: p-dev320“) to see whether they can shed any light on it and help you to discover why it isn’t working.
