Oh no! You have lost your connection to EA servers!

[Markincac4]

Unable to even load Plants Vs Zombies: Garden Warfare 2 (on PC) due to continuous "lost your connection to EA servers" message. I have not been able to play the game since I bought it yesterday. The game will not get past the splash screen. The flower dances in the corner then I get the message again. I have been hitting "ok"/try again for the last couple hours. What's going on?

The game has not ever loaded correctly?  It always disconnects after the first loading screen?

-------

Try unplugging your router and modem for ~5 minutes and replug them.

-------

If you have antivirus/internet security/extra firewall software (eset, norton, mcafee, etc).  As a test you may try disabling them temporarily and see if it solves it.  If it does, re-enable the program and add exceptions for PvZ:GW2.  Software like Peerblock would also block the connection likely.

------

You may try uninstalling and reinstalling Origin.  I doubt this is it judging by the message but it's worth mentioning.
