Everytime I wake my PC up, Battlenet App tries to reconnect automatically. But it gets stuck in the Connecting mode for at least 5 mins, much longer than the current production app. With the production app, I can manually click a button to reconnect which is quicker, but in beta, I have to wait or force the app to close and restart.
I am having this problem as well. I have to exit the app from the system tray and relaunch it to be able to connect.
I have the same problem like Seraphjoe describes
