2. Temporarily Change Your Network or Use a VPN
ISPs sometimes block certain internet traffic while trying to manage network speed and safety. If Battle.net or your game needs access to something your ISP has blocked, this error can appear. In this situation, switching to a different internet connection or using a VPN may help fix the problem.
3. Change Your Region in the Launcher/Game Settings
Battle.net uses different servers around the world to handle game downloads and updates. If your region’s server is too busy, switching to a different region can help.

Custom launcher or game settings sometimes stop games from working correctly. Resetting these back to their default settings often resolves strange errors like BLZBNTAGT000008A4.
5. Limit the Usage of Network Bandwidth in the Game Settings
You need a stable internet connection for the game to download or update successfully. Sometimes, having a very fast but unstable connection (especially on wireless broadband) can trigger this error. Limiting how much bandwidth the game can use may help.
6. Use the Mini-Client Setup of the Game
If you still have problems with the launcher or game, you can try using the game’s mini-client setup. Installing this can update your Battle.net launcher and may resolve the issue. Note: not all games offer a mini-client.
