Netflix Playback Error N8156 6205

The error you're seeing is related to the Silverlight plugin, which Netflix uses to play movies and TV shows on your computer.

This error is usually caused by one of two things:

  • A computer setting preventing Silverlight from storing files it needs to play your movie or TV show
  • An issue with the Silverlight plugin itself

To fix this error, follow the steps below for your Windows or Mac computer.


Steps for Windows

The Netflix.com player runs on the Microsoft Silverlight platform. Microsoft provides a free Fix It tool that you can download and run to resolve many Silverlight issues on computers running Windows 7 or later. Netflix recommends using the Microsoft Fix It Tool to resolve this error.

If the Fix it Tool didn't clear the error, or if you're running Windows XP or Vista, try the troubleshooting steps below.

Are you using Sandboxie software?

Sandboxie software may interfere with streaming movies and TV shows from Netflix.

  • If you are using Sandboxie software, close it and play your movie or TV show again.

Do you have anti-virus software installed?

Sometimes anti-virus software such as Webroot, Kaspersky, Immunet, or Intego VirusBarrier can interfere with the player Netflix uses to play movies and TV shows.

  • Disable your anti-virus software and play your movie or TV show again.
  • If a movie or TV show resumes after disabling your anti-virus software, this may indicate that the software could be outdated or unintentionally preventing the Netflix service from playing.

If you continue to see the error, there may be additional configuration settings within your browser settings preventing you from watching a movie or TV show. While trying to watch from a different browser you may not see these specific configuration issues. Please reach out to your anti-virus software manufacturer or a trusted IT professional for assistance with these issues.

  2. Restart your browser
    Sometimes restarting your browser can clear this issue.
    • Quit your browser, restart it, and play your movie or TV show again.
  3. Try another browser
    A browser extension, plug-in or add-on may be causing this error. Try playing your movie or TV show in another browser.

Make sure your Windows user account can access Netflix.com

The Microsoft Silverlight player on which Netflix.com runs requires that your Windows user account have administrative rights.

To confirm your account has admin rights, try the following troubleshooting steps:

    2. Click on the Start Menu in the bottom left hand corner of your screen.

    4. From the items listed, right-click (or press and hold on touchscreen devices) on your preferred browser icon (Netflix supports Internet Explorer, Firefox, and Google Chrome).
    5. Select Run as Administrator.
    6. If prompted, select Allow.
    7. Use this newly opened window to play your movie or TV show again.
      • Attempting to play again from the original browser window will likely result in the same error.
      • If these steps allow you to stream movies and TV shows from Netflix.com, your account does not have administrative rights. Talk to your computer manufacturer/administrator to add administrative rights to your account.
  2. Log in as another Windows user
    • If you are able to play your movie or TV show, the new user account has the needed permissions to use the Silverlight player.
