Key Points to Remember
- The P-Dev320 error code on Hulu typically points to connectivity issues with your device, app, or Hulu's servers.

- For optimal performance, consider using an Ethernet cable to connect your streaming device instead of relying on Wi-Fi.
Step-by-Step Guide
Try accessing Hulu on another device.

Consider using a different device. If you're currently using a mobile device, attempt to stream from a computer's web browser. Alternatively, if you're using a Smart TV, try using a mobile device instead. If Hulu functions properly on the alternate device, the issue may lie with the initial device rather than Hulu itself.
- Ensure your devices are regularly updated with the latest software releases as these often address common errors.
Reboot the Hulu app.

Shut down the app completely and then relaunch it. If the app becomes unresponsive or freezes, initiate a restart. On mobile devices, swipe up to fully close the app before reopening it. On Smart TVs, access the app's settings from your homepage to perform a shutdown.
Ensure your Hulu app is up-to-date.

Ensure Hulu is up-to-date. If automatic updates are disabled, make it a habit to manually check for updates regularly. Keeping your app current helps prevent common software glitches and malfunctions.
Clear your cache to resolve issues.

Regularly clear your cache. This action removes temporary data stored on your device, addressing specific loading problems.
- If you're using an iOS device, uninstall and reinstall the app to clear the cache.
Opt for a wired connection instead.

Switch to Ethernet connectivity. If your streaming device supports wired connections, utilize an Ethernet cable. If you're encountering connection errors, switching to Ethernet can be beneficial if your Wi-Fi signal strength is insufficient.
Verify if Hulu is experiencing downtime.

Refer to Downdetector to assess Hulu's operational status. A graphical representation of recent outage reports spanning 24 hours is available. A significant surge in reports typically indicates issues with Hulu's service. In such instances, patience is required until the matter is resolved.
