Frequently Asked Questions

What does Netflix error code UI-300-1 mean?
Netflix error code UI-300-1 means your device is unable to reach the Netflix servers. This is typically caused by an internet connectivity issue on your home network, a problem with the Netflix app on your device, an active VPN or proxy service, or occasionally a Netflix service outage in your region.
Why does Netflix keep showing UI-300-1 even though my internet is working?
Even if your internet works for other websites and apps, UI-300-1 can still appear if you have a VPN or proxy enabled (Netflix blocks many of these), if the Netflix app has a corrupt cache, if your Netflix app is outdated, or if your device's DNS settings are incompatible with Netflix's servers. Try disabling your VPN, clearing the app cache, and updating the app.
Does Netflix error UI-300-1 mean my account is suspended?
Not necessarily. UI-300-1 is a connectivity error, not an account error. However, if your account has a payment issue or has been flagged, it could contribute to connection failures. After ruling out network and app issues, try logging into your Netflix account at netflix.com on a browser to check your account status and payment information.
How do I fix Netflix error UI-300-1 on my smart TV?
On a smart TV, start by restarting the TV completely (unplug from power for 30 seconds). Then check that your TV's internet connection is active by opening the browser or another app. If the connection works, go to your TV's app store and update the Netflix app. If the issue persists, uninstall and reinstall Netflix from your smart TV's app store, then sign back in.
Can a VPN cause Netflix error code UI-300-1?
Yes. Netflix actively detects and blocks VPN, proxy, and anonymizing services. If a VPN is active on your device or configured on your router, Netflix may refuse the connection and display error UI-300-1. Disable your VPN completely, then restart the Netflix app. If Netflix works without the VPN, your VPN service is the cause of the error.
