I'm pretty much having the same issues, and it only started this week. I've been playing this game for 3 months and never had a single problem. Now it's a nightly thing with this 2002 and 90002 errors. I can connect to everything else in the world, except the game server. Lodestone, Mogstation, Forums, other games such as League of Legends, all websites, zero issues. It's just the lobby and game server. I don't know if my character is bugged or what the problem is, and it's getting extremely frustrating.
