Thank you fro the update meowning.

I would suggest closing any programs running in the background (such as Discord) even if you don't think it will interfere.

Make sure you make an exception on your anti-virus/firewall for Final Fantasy XIV.

Check the following Port Ranges on your router/modem to ensure that the following Port Ranges have been opened/forwarded/triggered:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040
Your ISP may forward these ports for you.*

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