Frequently Asked Questions

What does Netflix error code UI-122 mean?
Netflix error code UI-122 means the app has outdated or corrupted account information stored locally on your device. Netflix is unable to verify your account details and is asking you to sign out and sign back in to refresh that data.
Will I lose my viewing history or profiles if I sign out to fix UI-122?
No. Signing out of Netflix on a device does not delete your account data, viewing history, watch list, or profiles. All of that information is stored on Netflix's servers and will be fully restored as soon as you sign back in.
Why does Netflix error UI-122 keep coming back?
If UI-122 keeps recurring, the most common causes are an outdated version of the Netflix app, persistent corrupted cache data, or an account issue such as a billing problem or password change that keeps invalidating your stored credentials. Make sure your app is updated to the latest version and check your account status at netflix.com.
How do I fix Netflix error UI-122 on a Smart TV?
On a Smart TV, sign out of Netflix through the app menu, then power cycle the TV by unplugging it for 30 seconds. If the error returns after signing back in, go to your TV's app settings, clear the Netflix app's cache and data, and reinstall the app. Also check that your TV's firmware is up to date, as outdated firmware can cause app authentication issues.
Does Netflix error UI-122 mean my account has been hacked?
Not necessarily. UI-122 is most commonly caused by routine data sync issues, app updates, or billing changes — not account compromise. However, if you notice unrecognized profiles, viewing history you do not recognize, or unexpected account changes, go to netflix.com, change your password immediately, and sign out of all devices under Account > Security > Sign out of all devices.
