Yes my NAT settings are open I always do a cache clear. The only way I can get onto my main account is if I log in on a different account, then switch accounts. I never get to play or grind the game because it’s too hard to get on.
Thanks for the confirmation - Couple added questions:
Are you on a VPN?
Do you have to do the alt account workaround with every launch?
And finally, do you find that you will regularly get disconnected from the game mid-play session?
I'm tracking a few other cases similar to this. We unfortunately have not been able to reproduce this block on our side at all, despite trying to do so for a long time, so looking into affected players accounts is our only lead.
Can you please also DM me your gamertag?
