Can no longer launch the game (HTTPS System Error)

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

Could you try the following:


-Make sure your fire wall or antivirus program is not interfering with the game

- Check to see if the following port ranges are opened on your router. You can contact your ISP and request they open them for you:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

-Try disabling background applications and do a clean boot by opening the task manager and selecting the “Start up” tab. Disable everything and then restart the PC.

I have done that. It is not a network issue because it boots just fine on my brothers computer, who is connected to the same modem as I am.
