Hi,
This forum is for technical support on the Battle.Net Desktop App.
Modern Warfare II is produced by Activision, not Blizzard; please refer to Having Problems with Call of Duty? Read this first! pinned at the top of this forum.
If you google “disconnected from cod servers status goldflake”, you will find a few pages with information, this one for example… where you will find:
The Status Goldflake error is quite simply an error message that occurs if the user puts their system into some kind of power-saving state, such as the PlayStation’s Rest Mode, and tries to go back onto the game.
I hope this helps.
