A streaming error occurred. 
Error Codes: 2231, BLZBNTAGT000008B6, BLZBNTAGT000008B7

Streaming is the method we use to install and update our games. It allows you to play before the installation or patch is completely finished. If you choose to play before the game is completely installed or patched, the stream will continue to download missing data while you play.

This error means Battle.net Agent (the process that installs and patches our games) couldn't stream necessary files. Follow the steps below to resolve this issue.

  1. Our games require an up-to-date operating system to run properly. Run Software Update to be sure you're using the most recent version.
  2. Proxy servers can cause connection errors and may be enabled by mistake or by a malicious program. Disable your proxy.
  3. Security software may interfere with Battle.net Agent and prevent it from running properly. Disable or temporarily uninstall any security programs.
  4. Run Scandisk to check for hard drive errors.
  5. Programs running in the background can conflict with streaming downloads. Try closing background applications.
Advanced Troubleshooting
  1. If your network cache contains old or conflicting information, it will cause update issues. Resetting your DNS cache can resolve these conflicts.
  2. Reset your network devices, which may become flooded with data and drop the connection to your service provider.
  3. Check your network configuration to find issues with your firewall, proxy, router, or port settings.

If the issue persists, please allow Battle.net Agent to completely finish the download before you click Play.
