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

This error means that the Battle.net Update Agent couldn't open files to initiate streaming. 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.

Windows

  1. Disable your proxy. Proxy servers can cause connection errors and may be enabled by mistake or by a malicious program.
  2. Security software may interfere with the Battle.net Update Agent and prevent it from running properly. Disable or temporarily uninstall any security programs.
  3. Programs running in the background can conflict with the streaming download process. Try closing background applications.

Mac

  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. If there is not enough disk space available for critical game files, the game will not be able to update completely. Ensure that you have enough disk space to patch the game. 
  3. Reset your network devices, which may become flooded with data and drop the connection to your ISP.
  4. There may be a hard drive issue preventing the downloaded files from writing to your disk. Run the Repair Disk Permissions and Repair Disk utilities to try repairing any bad sectors.
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. Check your network configuration to find any issues with your firewall, proxy, router, or port settings.
  3. Programs running in the background can conflict with the installation or update process. Try closing background applications.
  4. Security software may interfere with the Battle.net Update Agent and prevent it from running properly. Disable or temporarily uninstall any security programs.

If the issue persists, please allow the Battle.net Update Agent fully download game data prior to pressing Play
