Common Problems

Whoops! Looks like something broke decrypting a file. Give it another shot.
Error Code: BLZBNTAGT0000085C

The Blizzard Battle.net desktop app cannot decrypt content files. Content files are encrypted when they are for a game or patch that is not released yet. You might see this error when your Blizzard Battle.net desktop app can't reach our servers to obtain a decryption key.

Note:If you're receiving this error after installing StarCraft II with a physical disc, delete the installation folder and download the game instead.

Windows

  1. Update or temporarily uninstall any security programs, which may mistakenly identify the login module as a security threat.
  2. Close all other applications to resolve software conflicts and free up resources.
  3. Low disk space may cause decryption errors. Uninstall unused programs or delete files to free hard drive space, and try again.
Advanced Troubleshooting
  1. Disable any proxies that may interfere with the login module.
  2. Check your network configuration to find any issues with your firewall, router, or port settings.
  3. If you're playing on a public or corporate network, the network's policies and security settings may interfere with retrieving a decryption key. Try connecting from a different network.
  4. Delete the Battle.net Tools folder to automatically rebuild outdated or corrupt files.
  5. Temporary installation files can cause errors during decryption. Delete all temporary Blizzard files.
