Good morning and thank you for posting in the Final Fantasy XIV Technical Support Forums.

Are you connected directly to the router through Wifi or are you using an ethernet cable? If you have not done so already, could you try the following:

Open the following ports ranges on your router:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

These are remote ports in your router’s firewall. They designate what can send information to your PC and what cannot. These specific ports are used by the game to connect to the local client.
