Quick Note: Prerequisites and Initial Checks

Before you start troubleshooting, make sure to:

Check your internet connection – a slow or unstable connection can cause streaming errors.
Restart your Windows 11 device – this can clear temporary glitches.
Ensure the Netflix app is updated to the latest version.
Verify that your Windows 11 system is up to date with the latest updates installed.

These basic checks can often resolve many common issues, including error UI3012.

Step 1: Restart the Netflix App

Sometimes, the Netflix app might run into temporary glitches that cause errors. Restarting the app can help clear these.

Close the Netflix app completely. To do this, click the X button or press Alt + F4.
Press Ctrl + Shift + Esc to open Task Manager.
Look for any Netflix-related processes under the “Processes” tab.
If found, select them and click “End Task” to fully close the app.
Reopen Netflix and try streaming again.

This step ensures the app starts fresh without leftover errors from the previous session.

Step 2: Check Your Internet Connection

Netflix requires a stable internet connection to stream content smoothly. Error UI3012 can occur if the connection is slow or unstable.

Open a web browser and visit any website to confirm your internet is working.
If pages load slowly or don’t load at all, try restarting your router by unplugging it, waiting 30 seconds, and plugging it back in.
Consider connecting your device directly to the router via an Ethernet cable for a more stable connection.
After the connection is stable, reopen Netflix and check if the error persists.

Improving your internet connection is critical because Netflix requires consistent bandwidth to deliver its content.

Step 3: Update the Netflix App

Running an outdated Netflix app can cause compatibility issues, leading to errors like UI3012.

Open the Microsoft Store on your Windows 11 device.
Click on the profile icon in the upper right corner and select “Downloads and updates.”
Click “Get updates” to refresh all your installed apps, including Netflix.
If an update is available for Netflix, it will start downloading automatically.
Once updated, launch Netflix and try streaming again.

Keeping apps updated ensures you have the latest fixes and improvements from the developers.

Step 4: Clear the Netflix App Cache

Sometimes, cached data can become corrupted and cause streaming errors. Clearing the app cache refreshes this data.

Press Win + I to open Windows Settings.
Go to Apps > Installed apps (or “Apps & features”).
Find Netflix in the list and click the three-dot menu next to it.
Select Advanced options.
Scroll down and click the Reset button.
Confirm the reset — this will clear the app’s cache and data.
Open Netflix again and check if the error is resolved.

Resetting the app clears out corrupted files that could be triggering the UI3012 error.

Step 5: Update Windows 11

Outdated system files or missing Windows updates can cause compatibility problems with apps like Netflix.

Press Win + I to open Windows Settings.
Navigate to Windows Update from the sidebar.
Click Check for updates.
If updates are available, install them and restart your PC.
After restarting, try opening Netflix and streaming your content.

Keeping your Windows 11 system updated ensures better app compatibility and security.

Step 6: Disable VPN or Proxy Services

Netflix sometimes blocks streaming when using VPNs or proxies, which can cause error UI3012.

If you are using a VPN or proxy, temporarily disable it.
To disable a VPN, open the VPN app and disconnect.
To disable a proxy, press Win + I > Network & Internet > Proxy, then turn off manual proxy setup.
Restart Netflix and check if you can stream without the error.

Netflix enforces regional content restrictions, so VPNs and proxies can interfere with streaming.

Step 7: Reinstall the Netflix App

If none of the above steps work, reinstalling the Netflix app might be necessary to fix corrupted app files.

Press Win + I to open Windows Settings.
Go to Apps > Installed apps.
Find Netflix, click the three-dot menu, and choose Uninstall.
Confirm the uninstallation and wait for it to complete.
Open Microsoft Store, search for Netflix, and install it again.
Launch the app and try streaming your content.

Reinstalling ensures you have a clean installation free from corrupted or missing files.
