I can't connect

Not really a lot of info to go on.

Have you rebooted your system?

Have you rebooted your modem/router?

Is it just to this game or is it other games too?

Are you connecting to the app or not even that?

Steam or EA?

My suggestion is check the above and it may come down to their is simply a connection problem downstream to the servers which you have little choice but to try again later and see if it has resolved itself.

If you can connect to the app then run the scan and repair feature to see if that works.

Good Luck
