Hulu error code p-dev320 means the app failed to complete playback: it could not maintain a working connection between your device and Hulu’s servers. It shows up on smart TVs, phones, streaming sticks and browsers alike, and it is almost always a network or app-data problem on your side rather than your account. The fixes below run from the thirty-second checks to the full resets. Start at the top and stop when the error clears.
First: Is It Actually Hulu?
Before changing anything, check whether Hulu itself is having an outage. Search “Hulu down” on a status site like Downdetector, or check Hulu’s support social accounts. If there is a spike of reports, p-dev320 is on their end and the only fix is waiting. If the error is just you, keep going.
1. Restart the App and the Device
Fully close the Hulu app rather than backing out of it. On Android: Settings > Apps > Hulu > Force Stop. On iPhone and iPad: swipe up from the bottom of the screen and swipe the Hulu card away. On smart TVs and streaming devices, use the device’s app or channel management menu, or simply unplug the device from power for 30 seconds and plug it back in. A full device restart clears the temporary network state that often triggers p-dev320 in the first place.
2. Clear the Hulu App’s Cache and Data
A corrupted cache is the most common cause of persistent p-dev320 errors. Clearing it forces the app to rebuild its local data:
- Android: Settings > Apps > Hulu > Storage > Clear Cache, then Clear Data.
- Fire TV: Settings > Applications > Manage Installed Applications > Hulu > Clear Cache, then Clear Data.
- Roku: no cache menu exists. Remove the Hulu channel, restart the Roku (Settings > System > System Restart), then reinstall Hulu.
- iPhone/iPad: there is no per-app cache option; offload or delete the app and reinstall it.
You will need to log back in afterward. This step fixes the error more often than any other.
3. Check Your Internet Connection
P-dev320 often appears when the connection is up but unstable: brief dropouts that browsing survives but streaming does not. Run a speed test on the same device. Hulu needs roughly 3 Mbps for on-demand video and more for live TV, but consistency matters more than raw speed. If you are on Wi-Fi, move closer to the router or switch to the 5 GHz band if your router offers it. Restart the modem and router by unplugging both for 60 seconds. If you are not sure how to log into your modem to check its status lights, our guide to finding your router’s IP address covers it.
4. Update the App and the Device
An outdated Hulu app on a recently updated device (or the reverse) is a classic p-dev320 trigger. Check for a Hulu update in your device’s app store. Then check the device’s own system updates: Roku under Settings > System > System Update, Fire TV under Settings > My Fire TV > About > Check for Updates, Apple TV under Settings > System > Software Updates, and smart TVs under their support or software menu.
5. Try a Different Device or Network
This is a diagnosis step, not a fix. Open Hulu on your phone using mobile data. If it plays fine there but fails on the TV, the problem is your home network or the TV’s app, and you can stop worrying about your account. If it fails everywhere on every network, the problem is at Hulu’s end or with your account, and it is time to contact Hulu support.
6. Disable Your VPN or Proxy
If you watch Hulu from Australia you are likely using a VPN or smart DNS, and p-dev320 is one of the errors Hulu throws when it detects one. Disconnect the VPN and test on your normal connection to confirm the cause. If the VPN is the trigger, try a different server location in the same country, or switch the VPN protocol in its settings. Free VPNs are a common cause here: their servers are shared by thousands of users and are the first IP ranges streaming services block. If you are relying on one, our best free VPN rundown covers which free tiers actually hold up for streaming, and our Hulu Australia guide walks through the whole setup from scratch.
7. Reset Your Network Settings
On mobile devices, a network settings reset clears saved Wi-Fi networks, Bluetooth pairings and DNS overrides that can interfere with streaming. On iPhone: Settings > General > Transfer or Reset > Reset > Reset Network Settings. On Android: Settings > System (or General Management) > Reset > Reset Network Settings. You will need to re-enter your Wi-Fi password afterward.
If Nothing Works
Contact Hulu support with your device model, app version and the exact error code. Also mention whether other devices on the same network work. That information saves a full round of back-and-forth. And if you hit other streaming errors while you are at it, the same fix order applies to most of them: our guide to Disney error code 83 follows an almost identical pattern.
