Game fresh installed.
Router rebooted etc.
Internet works perfectly, all games works.
Only Battlefront 2 is not connecting to any MP games.

Me too.
I had to re-install on different hard drive on my system last week (last patch wouldn't fit on SSD so i had to move it to HDD)
since then, I can play arcade mode, access my account, but ERROR 1066 on all multiplayer modes

Tried repair, not helping.
All updates are there - it's a fresh installed game.

As in the case of @nfourpack, a game reinstall may be the fix.
