Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.
Something like this is usually caused by a connection issue. Most likely, there is some configuration on your home network that is interfering with the game. Please check some of the following:
1) Reset your router by turning it off for a few minutes, then back on.
2) The game will use the Internet Explorer web browser to connect to the internet. Open Internet Explorer, then open the "Tools" setting, go to "Internet Options" and adjust the following settings:
- Under the "General" tab, please delete ALL browser history.
- Under the "Security" tab, please move the slider to the lowest possible settings or no higher than "Medium"
- Under the "Privacy" tab, click “Advanced” and select ‘Accept’ under both First Party and Third Party Cookies.
- Under the "Advanced" tab, please make sure that "Allow software to run or install even if signature is invalid" is CHECKED.
- Make sure that all SSL and TLS (EXCEPT SSL 3.0) are CHECKED. [SSL 3.0 should be UNCHECKED]
- Hit "Apply" to save the settings, and then "OK, to close the Internet Options menu.
- Right-Click on the FFXIV launcher icon and select "Properties"
- Go to the "Compatibility" tab, and change the compatibility mode to "Windows 7"
- Hit "Apply", then "OK" to save the changes.
- Please RESTART your PC now. Once your PC has been restarted, Right-Click the FFXIV launcher icon once more and select "Run as Administrator"
3) Preferably, use a wired connection with an Ethernet cable as opposed to wireless.
4) Check if the following port ranges are open in your router. You can contact your ISP and request that they open them for you:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040
5) Make sure your anti-virus/firewall has the appropriate exceptions for Final Fantasy XIV
We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
