When i try to log in any set ( classic or bfa ) and I enter game all at once, all account get "you have been disconnected error xxxx" If i log in one at a time via isboxer, one gets in and any others get that error. If i log in via the bnet app, no boxing software, i can log as many as i want

I have rebooted, I have used dev build and non dev build. any ideas?
