Please help me i am getting 90002 bug whenever i try to login

Whenever i click on my character to log in i get Connection Lost 90002 it been more than a day, happened on 21th Jan near 1 a.m ST
Frequency, it happens when every time i try to log in
server is Odin
Character name is Nana Doll
The place that shows where i am located is at The Wreath of Snakes (Extreme)
i was using my White Mage lv70 while playing with a party.
using Wi Fi , pc windows 10.
I have adjusted my internet settings according to instructions you have posted in other threads in this forum. I have also flushed my DNS. None of this has alleviated the regular disconnects, the system still shows that i am logged in and it does not let me log in when i click on my character it kicks me out to the start screen.
I wish you can help me, i am a fc leader and i have stuff to take care of. :(

Good morning and thank you for posting on the Final Fantasy XIV Technical Support Forums.

When did this start happening? Were you originally disconnected and then ran into this problem when you tried to log back in?

Are you able to log into other characters?

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
