How to Fix Error Code UI-800-2

  1. Restart the Netflix App

  2. Restart Your Device

    Make sure to fully power off rather than just putting the device to sleep. A true restart clears memory and active processes.

  4. Clear the Netflix App Cache and Data

    Clearing app data will sign you out of Netflix. Have your Netflix email and password ready before proceeding.

  5. Deactivate Netflix on Your Device

  6. Reinstall the Netflix App

    On some smart TVs, removing a built-in app may require a factory reset of the TV if the app cannot be found in the app store. Check your TV manufacturer's support page first.

Frequently Asked Questions

What does Netflix error code UI-800-2 mean?
Error code UI-800-2 means that the Netflix app on your device needs a data refresh. The stored app data — such as cached account information, settings, or session tokens — has become corrupted or outdated, preventing the app from communicating properly with Netflix's servers.
Will clearing Netflix data delete my watchlist or viewing history?
No. Your Netflix watchlist, viewing history, profiles, and preferences are all stored on Netflix's servers, not on your device. Clearing the app's local data or even uninstalling and reinstalling the app will not affect your account content. You will simply need to sign back in.
Why do I keep getting Netflix error UI-800-2 after fixing it?
If the error keeps coming back, it may be caused by an unstable internet connection, an outdated device firmware that is no longer fully compatible with the Netflix app, or a device that Netflix no longer supports. Check for device and app updates, and consider whether your streaming device is more than 5–7 years old, as older hardware may no longer meet Netflix's minimum requirements.
Does Netflix error UI-800-2 affect all devices at once?
Not usually. This error is typically device-specific, meaning it affects only the device where the cached data has become corrupted. If you see the error on multiple devices at the same time, it is more likely a Netflix server outage or a network issue on your end. Check netflix.com or downdetector.com to confirm.
How do I fix Netflix error UI-800-2 on a Roku device?
On Roku, press the Home button 5 times rapidly, then press Up once, Rewind twice, and Fast Forward twice. This triggers a hidden Roku system refresh that clears Netflix's stored data. If that does not work, go to Settings > System > Advanced System Settings > Factory Reset, or remove the Netflix channel and reinstall it from the Roku Channel Store.
