You are using an outdated version of the client.
Errors: BLZBNTBGS0000001C, BLZHSBGS0000001C

The client you are using to log in to the game is out of date or there is a mismatch between the client and server versions. This error can occur if there was a recent update to the game and you haven't patched. Follow these steps to resolve the issue:

  1. Use the Battle.net Desktop App to launch the game. Any pending game updates will download once the application is opened. 
  2. Try repairing the affected game to make sure there are no corrupted game files. 
  3. If the issue persists, uninstall the game client and download a new copy of the installer from the Battle.net Game Downloads page.
