Netflix Error UI-800-3 — What Causes It & How to Fix It

What Does This Error Mean?

Error UI-800-3 means the Netflix app on your device needs to be refreshed. It's caused by outdated or corrupted app data — not your internet connection. Signing out and back in, or reinstalling the app, almost always fixes it.

Affected Models

Netflix on Smart TV
Netflix on Roku
Netflix on Amazon Fire Stick
Netflix on PlayStation
Netflix on Xbox

Common Causes

Corrupted Netflix app data stored on the device
Outdated Netflix app that needs updating
Device has not been fully restarted in a long time

Cached app data has become outdated and is causing conflicts

How to Fix It

Fully power off your device — unplug it from the wall, wait 30 seconds, then plug it back in.

A full power cycle (not just standby) clears the device's memory and often resolves UI-800-3 immediately.
Sign out of Netflix on the device, then sign back in with your email and password.

On most devices: open Netflix > tap the menu > Sign Out. This refreshes your account session on the device.
Clear the Netflix app's data or cache in your device's settings menu.

On Fire Stick: Settings > Applications > Manage Installed Applications > Netflix > Clear Data. Steps vary by device — search your device model + 'clear app cache'.
Uninstall the Netflix app completely, then reinstall it from your device's app store.

This removes any corrupted installation files. Your watch history and preferences are saved to your account online — nothing is lost.
Deactivate the device from your Netflix account at netflix.com/account, then sign in again on the device.

Go to netflix.com > Account > Manage Access and Devices > Deactivate the affected device. Then open Netflix on the device and sign in fresh.

This is a software issue. All fixes can be done without a technician.

Frequently Asked Questions

Does UI-800-3 mean my Netflix is cancelled?

No. This error is about app data on your device — not your account status. Your subscription is unaffected. The fix is on the device itself.

Will clearing Netflix app data delete my watch history?

No. Your watch history, My List, and preferences are stored on Netflix's servers. Clearing app data on your device only removes local temporary files.

UI-800-3 keeps coming back after I fix it — why?

If it returns repeatedly, the Netflix app on your device may have a persistent bug. Check for a firmware update for your TV or streaming device — manufacturers often fix these issues in system updates.
