If you are using a VPN client or proxy server, follow the steps below to uninstall or disable these two anonymity solutions to avoid a conflict with the Netflix app:

• Once you are inside the tab Properties, go to the tab Connections(from the menu at the top), then click on LAN settings (At Local Area Network LAN Configuration).

• Inside the menu Configuration of the  local area network (LAN), go ahead and click on the proxy server  and then uncheck the box associated with  Use a proxy server for your LAN.

After you have disabled the server proxy, you will restart your computer and check if the problem is solved at the next system startup.

B. Uninstalling the VPN client

Delete Netflix cookie

It turns out that one of the most common instances that will produce this error is a partially corrupted cookie or incorrectly saved cookie data that is forcing Netflix to terminate the connection.

If this is the root cause of the problem, there are 2 different possible solutions you can implement:

• You can perform a full cleanup to clear your browser's entire cache folder and also delete the current cookies your browser is using.
• You can ONLY delete cookies that belong to Netflix.

Note: If you decide to go with the focused approach, you should only delete the cookies associated with Netflix. But if you're dealing with some kind of interference caused by a cookie that's outside of Netflix's purview, the best approach is to perform a full cookie and cache data clear.

But regardless of which option you want to choose, we have put together 2 separate guides that will walk you through the bot processes:

A. Clear Netflix cookie and cache

• Open the browser in which you are encountering the error Error NSEZ-403, visit the page dedicated to deleting Netflix cookies.

Note: This page contains an automated Netflix script that will automatically delete dedicated cookies stored by Netflix on popular browsers. This will work on the vast majority of third-party browsers, as well as Internet Explorer and Edge.

• Once you successfully visit the above page, you will be automatically logged out of your Netflix account. Please revisit the Netflix page and log in to your account again by inserting your credentials again.

• After you log in with your Netflix account again, try streaming content once more and see if the issue is now resolved.

B. Delete all cookies and cache from your browser

In case clearing Netflix cookies is not enough for you or if you are using a browser that is not compatible with the Netflix cleanup script, it might be better to clear all cookies and cache from your browser.

Note: If you are using a chromium based browser that is not covered in your guide, you can simply follow the guide for Google Chrome.

If you have already tried clearing cookies and cache and you are still encountering the same NSEZ-403 error, try the next potential solution listed in the next section.

Depending on your browser of choice (Mozilla Firefox or Google Chrome), follow one of the instructions below to ensure that extensions or add-ons are not allowed to run.

A. Disable add-ons within Firefox

If you are using Firefox, the quickest way to resolve this issue is to start Firefox in Safe Mode.

Safe Mode will start Firefox without any add-ons (extensions or themes) installed. If the problem no longer occurs while add-ons are disabled, you can conclude that one of them is causing the problem while Firefox is running in normal mode.

Here's how to check if this is true:

• Start by opening Firefox and typing the section about:support within the navigation bar. Then press Enter to directly access the menu Troubleshooting information.
• Once you are inside the menu Troubleshooting information, Click on Restart with plugins disabled(At Try safe mode). When the confirmation window appears, you need to click on Restart once again.

Some users who have also been experiencing issues with Error NSEZ-403 have managed to fix the problem after disabling hardware acceleration from the browser settings.
