Well, I was just playing happily for a few hours until I got disconnected, and now the 2002 error is coming up for Chaos, but I'm able to log on to Elemental so I'm pretty sure it doesn't have anything to do with firewall or security or anything of the sort since accessing the Japanese server takes 1 second. And I was in game already so it's not like I installed some update that broke the connection since I was logged on 40min ago before the game kicked me out.

Also, I tried pinging the server and that works fine.

If it's a problem with too many people wanting to log on, and you're tackling that issue by kicking people that were actively running dungeons out of the game that's not really ok. I'd rather you brought back the 10min afk disconnect thing.

This is really upsetting and I hope that the transfer to real European servers will happen sooner than later and fix a few things.

I've been able to contact a few people from the same linkshell to let them know I had gotten dc'ed and they are having the same issue.

Please let us know what's going on I'm surprised that no official explanation has been given since I've seen quite a few other posts regarding this..
