From the Settings of your TV streaming device, consider setting the resolution to 1080P, and then launch Netflix to check if you are no longer being prompted with the Error code.

Fix 7: Change the DNS Settings

Another reason for the Netflix error code may be due to the DNS servers that cannot translate the web addresses of the Netflix servers correctly.

Fix 8: Check Your Wifi Connection

The Netflix code UI-800-3 message can also pop up if the issue lies in the internet connection.

If your WiFi is not working properly or there are weak signals, it is quite normal for the Error message to pop up. So, you must make sure your internet connection isn’t the underlying reason behind this error.
