FFXIV loses connection

This has been frequent of late. Not yet all the time, but every day I can play at least once does the server (Siren) lose connection and kicks me out. After that takes long time to log back in cause of 'log out process' This is starting to get annoying and who tells us it won't get worse over time?

Before you judge and blame my internet I have a consistent 400+mb/s with excellent connection... So no it is not my internet. I'd like to play without getting kicked out when I do not even idle...
