F-Secure SAFE Web Browser protection blocks Battle.net
Since latest F-Secure SAFE (PC) update which had improved family security settings, SAFE keeps destroying Battle.nets connection.
When browsing protection goes on, Battle.net disconnects, and cannot reconnect even after browser protection is ended.
Only way to re-establish the connection is to kill SAFE's protection and Battle.net connects instantly.
This didn't happen with previous software version, so something fishy happened with the update.
The application cannot be working as intended this way.
