I have the same problem and added a post in the bug forum.

It drives me crazy!!!!

I am on my personal network and the behavior is so...

1. 100% of the time it bombs within a few minutes of logging in for the first time
2. Drops 2-3 times in a 2 hours session
3. And for whatever reason around 11PM EST it tends to drop. Like clockwork.

SQUEENIX, WHAT IS THIS DAMN 30002 ERROR!!!!!!!
