If you are receiving a specific error code (such as BLZBNTAGT00000BB8), you can search for the error code on our Support Site. The error code's page will have more specific troubleshooting. If you do not receive an error code, the steps below may resolve problems in which the Battle.net Desktop Application can’t download data or update game files.
Restart your computer to resolve problems caused by programs and services running in the background.
Disable or temporarily uninstall any security programs, which may mistakenly identify the login module as a security threat.
- World of Warcraft addon managers can prevent Agent from updating game files. Disable or temporarily uninstall these programs, restart your computer, and try again.
If you're using a wireless connection, optimize your internet connection to rule out a connection issue.
Run the Blizzard Battle.net desktop app in Administrator Mode to address many installation, patching, networking, and start-up errors.
Run the repair tool to repair any damaged game files.
