Keep Repeating Disconnect by server (90000/90002) and then 2002 after patch 2.3

To: FF14 Dev Team,

Hi, I got some disconnect issue here,
I was randomly disconnected by the server right after patch 2.3!
However, its just 1-2 times a day before so i didn't worry about it until yesterday!
I was keep disconnected by server(90000/90002) every 5mins or right after the login loading, and then 2002 error (fail to connect lobby) for almost whole yesterday!
i tried to ping the server and looks normal!
I am able to watch youtube/Internet Browsing/play other JP/UK/US online game without any issue.
I also reset my router as well!
I also tried to turn off Anti-virus/Firewall but it's didn't help!
frds of mine who using the same ISP in the same area also don't have any issue about the disconnecting.
That's why I thought it was my computer issue at first!
However, somebody else in game forum told me that he got the same issue after patch2.3 as well!
It's ok for me now but I afraid the FFXIV game connection will drop again anytime later!
I hope you can fix this ASAP, Thanks!
