[Error 90002] Kicked from instance, cannot log back in.

I am having the same issue, trying to complete the red mage 56 instance and it boots me and cannot log in.

There needs to be a grace period to the queue if the server disconnects you!!!!

Yeah that's really what frustrates me more than the errors. Other MMOs have tiny windows where you keep your spot if you simply disconnect.
