I was on one of my accounts earlier and stayed logged in for about 5 hours. After logging out to get on my other account, I was met with the prompt, "ID or password is incorrect" when I can log into Lodestone and Mog Station fine. Changing password also wasn't an issue but the authentication server in the Loader client won't let me through. Now when I try the account I was on which I logged off from not too long ago won't go through neither.

Log in server issue... please assist.
