Titanfall PC Connection

Hello everyone, I hope someone is able to help me.

I have purchased Titanfall for PC through Origin.

After complete installation, I launched and started the game, and I end up on a still image of battle cruisers in the sky with a spinning circle on the bottom right. After a while, the game gives up and tell me it cannot connect to server.

I read up on the online help, and open TCP and UDP port on both router and PC. It didn't help.

Then I looked at the inbound port setup for Battlefield 3, apply the same rule and opened all ports to the titanfall.exe. It still doesn't work. Does anyone have any clue as to what I did wrong?
