Clearing the cached data help to make some space on your device by removing temporary files and improving streaming conditions, as well as getting rid of possible corrupted files that got randomly installed.
2. Check your Internet connectivity

Be aware that to fully enjoy your video streaming experience, Hulu requires the following Internet speeds:
- 3.0 Mbps for the Hulu streaming library
- 8.0 Mbps for live streams
- 16.0 Mbps for 4K content
Streaming with lower speed is also possible, which will reduce the video quality.
Other useful fixes:
If all else failed, you should consider trying these solutions as well:
- Ensure that the Hulu app and your device are updated
- Many problems are caused by outdated apps. So check for available updates in the apps store or your device’s settings menu.
- Perform a power cycle
- In your Hulu account page, remove your device by logging out completely. Then, log back in by re-entering your credentials. Try to launch Hulu again and see if the problem is solved.
- Whitelist an ad domain
- You might have completely blocked ads coming from Hulu by blocking the ads-e-darwin.hulustream.com domain. You have to whitelist it back on the proxy authentication server and it will most likely fix the issue.
As mentioned before, these steps are part of the basic troubleshooting recommendations, which should be easily done by any user. Nevertheless, if the error code P-DEV320 is on Hulu‘s side, you can only wait for them to fix the problem.
