[SUPPORT] Can't access the game for one of the following reasons:

You cannot access the game for one of the following reasons: 1)The game world is down for maintenance (which it is not) 2)You are accessing the game from a banned IP (my brother is currently playing without issues on the same IP and router) 3)Your internet connection is not stable (added MS to firewall, reset router, and checked IP config site)

What else can I do? I've sent a ticket to Nexon.

EDIT: I've had this error since yesterday at about 2pm. I was playing earlier that day.
