Fix UI-800-3 on Xbox One

Xbox One is slightly different from the other devices we’ve looked at. In order to fix the UI-800-3 error on your Xbox One, you’re going to have to check your DNS settings. 

First, we should explain what DNS does. Your DNS is responsible for translating human-readable website names into numeric IP addresses that computers can work with. If your DNS does not work properly, you will have trouble connecting to online services and websites.

The Netflix app on your Xbox One connects to Netflix’s servers to load and stream movies and TV shows. It uses DNS lookups during this process, so you need to ensure that your DNS settings are correct.

  1. Go to the Profile and System menu.
  2. Select Settings.
  3. Follow this path: General > Network Settings > Advanced Settings > DNS Settings.
Xbox One network settings
  1. Select DNS Settings
  2. Set your DNS to Automatic.

This should allow Netflix to connect using the best possible DNS server automatically. 

Fix UI-800-3 on Smart TV

It’s somewhat harder to fix the UI-800-3 error on a smart TV. This is because there are so many brands of smart TV out there, and each of them operate a little differently. However, there is one common solution that should work on every smart TV brand, be it Samsung, LG, Sony, Panasonic, Philips, or anything else.

When you reset your smart TV, you also force all of its apps to reset. You can combine this with the log-out method to fully reset your Netflix app settings. This should allow you to overcome the UI-800-3 error on any smart TV.

  1. Sign out of Netflix.
  2. Turn off your Smart TV.
  3. Unplug your smart TV for one full minute.
  4. Plug your TV back in.
  5. Sign back into Netflix.

General tips for the UI-800-3 error 

So, what if these fixes didn’t work?

The UI-800-3 error is a little bit tricky, and sometimes it’s caused by a variety of other issues. We’re going to walk through a few more solutions for the UI-800-3 error that check out a few different ways that this error can pop up.

These fixes should apply to a wide range of devices including video game systems, smart TVs, tablets, and smartphones. 

VPNs and the UI-800-3 error

The virtual private network (VPN) is a must-have safety and information security software. It encrypts all of the information that your device sends over the internet. Not even your internet service provider will be able to see your traffic when you’re running a VPN.

Additionally, there are Netflix shows that are only watchable in certain geographic locations. If you want to get access to Netflix UK, Netflix Canada, or Netflix USA, you can use a VPN to trick Netflix into thinking your computer is located in a different country. This is not an intended use case, however, and VPNs can sometimes cause the UI-800-3 error.

If you keep getting the UI-800-3 error while connecting through a VPN, try disabling it temporarily and see if it solves the issue.

Uninstall and reinstall Netflix

Uninstall Netflix

If the UI-800-3 error starts to appear after a Netflix update, you might need to uninstall and reinstall the app in order to fix it.

A fresh installation allows the Netflix app to completely reset its information. This should overcome any problems that have been caused by an update that went bad. This can also fix the issue after Netflix crashes or has another software problem.

It’s worth pointing out that not every device clears the cached data when it uninstalls an app. Certain systems will leave the cached data because that includes information such as user settings. You should clear your cache data for Netflix and then proceed with uninstalling it.

Check your WiFi

The problem could also be with your WiFi network.

The UI-800-3 error tends to pop up when a device has a poor connection to a WiFi network. This is because the app confuses a bad connection with problems accessing its data and cache.

This can happen if your device is too far away from your router, there are too many devices on your network, or you are just running some outdated WiFi technology. 

You should double-check your WiFi network settings and the signal strength to make sure that it’s not actually causing the issues.

Check your smart hub

This last fix applies to devices that are connected to a central smart hub. More often than not, this is going to apply to certain brands of smart TVs like Samsung.

Your smart hub interconnects all of the devices in your smart home’s ecosystem. It’s an essential part of staying in control of all of your Philips Hue lighting and other smart devices. However, it can cause some errors when connecting to a smart TV.

If you have a Samsung Smart TV, and it’s connected to a central hub, you might need to reset that hub in order to overcome the UI-800-3 error. 

Wrapping up

Most of the time, the UI-800-3 error pops up because you need to reset your app. This is an easy fix that should only take a few seconds. You might not even need to log out of your device to reset the Netflix app.
