How to Fix Netflix Error UI-800-3?

Netflix is the go-to streaming service for most of us to watch our favorite TV shows and movies.

However, many users have encountered the UI-800-3 error when launching Netflix on their Smart TV, even though it works fine on other devices.

This issue can be quite frustrating, but don’t worryโ€”Iโ€™ve done some thorough research and found several proven solutions to fix it.

Before getting into those fixes, letโ€™s first understand what the Netflix UI-800-3 error means and its causes.

What is Netflix Error UI-800-3 And What Causes It?

The Netflix error code UI-800-3 indicates that your device’s cached data needs to be refreshed, or thereโ€™s a network issue preventing Netflix from launching.

The error is typically accompanied by a message saying, โ€œCouldn’t connect to Netflix. Please try again or restart your home network and streaming deviceโ€ฆโ€

This is different from the UI-800-3 error that includes a specific code in parentheses, such as Netflix Error UI-800-3 (207003). However, some of the solutions Iโ€™ll cover in this piece may help fix those issues too.

Here are the highlights of some common causes of the Netflix error UI-800-3:

  • Corrupt Netflix app data and cached data
  • Network connectivity issues
  • Device issues

How to Fix Netflix Error UI-800-3

As simple as it may seem, the way to fix the Netflix error UI-800-3 is to clear the temporary files, app data, or all data stored on the device experiencing the Netflix issue.

But here are the list of workarounds that can help you whether you’re facing the issue on a Samsung TV or Sony TV:

1. Power Cycle Your Device

The first solution I’ll recommend you to perform to fix the UI-800-3 error on Netflix is to power cycle your streaming device.

This refreshes the device by clearing any cached data that might be causing the issue. Hereโ€™s how to do it:

  1. Turn off the device, whether itโ€™s a TV, console, or other streaming device, using the power button.
  2. Unplug it from the power source, and disconnect any connected cables for about 30 seconds to 5 minutes. This ensures any remaining power is fully drained.
  3. Once thatโ€™s done, plug it back into the power source and turn it back on.

Now, try launching Netflix again to see if the UI-800-3 error has been resolved.

2. Try a New Network

If you were connected to a home WiFi network when the issue occurred, try switching to a mobile network to see if it resolves the problem.

Plus, some users have fixed the Netflix error by changing their router’s DNS server. For example, if you were using Google DNS (8.8.8.8 / 8.8.4.4), try switching to Cloudflare DNS (1.1.1.1 / 1.0.0.1) by following your router’s manual for instructions on how to make the change.

Side Note: If the solution above didnโ€™t work, try resetting your network settings, then restart the network and reconnect. This can also help fix the issue.

3. Sign Out and Sign in Out the Streaming Device

Another way to reset Netflix on your streaming device and fix the UI-800-3 error is by signing out of your Netflix account and then signing back in. You have to make sure you have your Netflix login details handy before doing this, as you risk losing access to your account if you don’t.

Since different streaming devices may have varying ways to sign out of Netflix, hereโ€™s a general method you can follow:

  1. Go to the Manage Access and Devices page on your browser.
  2. Next, log in your Netflix account.
  3. Select the Sign Out button next to the device you want to sign out of.

It may take some time for the remote sign-out to take effect on the streaming device you’re having issues with. Once it does, log in again and check if the issue is resolved.

4. Clear the Netflix App Cache

Some streaming devices allow you to clear the app cache stored locally. This can help fix the Netflix error UI-800-3 without needing to uninstall the Netflix app. If your device supports this, itโ€™s worth trying to resolve the issue.

5. Reinstall Netflix

I also found out that you can fix the Netflix error UI-800-3 with the good olโ€™ uninstall and reinstall method. This deletes any corrupt data that could be causing issues and gives the app a fresh start on your device. However, this might not work for devices where Netflix is built-in.

If youโ€™ve installed the Netflix app yourself, you can check your streaming device manufacturerโ€™s guide for instructions on uninstalling and reinstalling Netflix. After doing this, see if the issue is resolved..

6. Reset Your Streaming Device

This is the last solution Iโ€™d recommend: resetting your streaming device. There’s a high chance it will fix the issue, as long as it’s not caused by a network problem. However, the downside is that this will completely wipe your device, restoring it to its original stateโ€”deleting all apps and data, just like when you first got it.

Final Thought

The solutions Iโ€™ve covered in this piece should help you fix the Netflix error UI-800-3 on your streaming device.

Most of these are pointers, so you’ll need to follow the specific steps for your device. I hope you find this guide helpful.
