ERROR You were disconnected from EA Online (1)

I'm having the same problem. I played it ok until yesterday when origin would just not connect. Lots of people are having the same issue as can be seen in this thread: http://battlelog.battlefield.com/bf4/forum/threadview/2955064773659668996/1/

All the replies they removed are from people saying in Portuguese that the same thing is happening to them.
It would be a hell of a coincidence if all of our firewalls just decided to block the game at the same time.

Hope this can be solved,
Daniel
