Hulu

Hulu is Disney's US streaming service for on-demand shows and live TV. On smart TVs, the most common complaints are playback errors such as P-DEV320 and stream-limit messages — both usually clear with an app update, a restart or by stopping a stream on another device.

Hulu Error P-DEV320: How to Fix It

P-DEV320 means the Hulu app on your device couldn't complete its connection to Hulu's servers — almost always the app, your internet or the device's software, not a broken device or account.

Frequently asked questions

What does Hulu error P-DEV320 mean?+

Hulu doesn't publish a detailed article for this exact code, but it is widely reported as a playback error that appears when the app can't communicate properly with Hulu's service — typically caused by an outdated app, a device glitch or a weak connection. Closing and reopening Hulu, restarting the device, and updating or reinstalling the app often resolves it.

How many screens can I watch Hulu on at the same time?+

Standard Hulu plans allow streaming on two screens at once. Hulu + Live TV subscribers can add the Unlimited Screens add-on to watch on any number of supported devices on their home network.

Why does Hulu say too many videos are playing?+

That message means your account has reached its simultaneous stream limit — two screens on standard plans. Stop playback on one of the other devices using your account. If you don't recognize the other streams, change your Hulu password to sign everyone out.
