Thank you for the update YoshiY.

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.*

You can also try a clean boot. Simply open the task manager and select the 'Start up' Tab. Disable everything here and restart the PC.

Make sure that you are using a wired connection with an Ethernet cable.

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