I am getting same error. 721. It won't let me connect to EA servers. Puts me in offline mode. I play the PC version.

since at least 3 or 4 hours ago can't connect to origin at first... now I can connect to origin but when I tried to connect in battlefront II... ERROR 721 says something like its unable to connect to EA servers...

I've found the answer. You should check your IP version. I've changed it from IPv6 to IPv4, and now everything is OK 🙂

Force closing the game, then restarting has worked every time for me. (Four times since launch.)

No, it’s a fresh download from after the PC beta ended and I uninstalled everything involved from that weekend.

If you could specify what application it was that'd be helpful please!
I'm having this problem and just doing a blanket "end task" on programs running in the background.

I was told that once you pre ordered the game we would have access two days before release date. Today is the 15th two days before the release date 11-17-17, and I still can’t access the game
