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

I apologize for the delay in our response to your concern. Please try the following troubleshooting as it may help resolve the issue you are experiencing.


Open the control panel of the PC and go to ‘Network and Internet’. Once there select ‘Internet Options’
- 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"
- 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"
*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

Lastly, we suggest to power cycle the router by shutting down the Router and leaving the power supply unplugged for 5-10 minutes.


If you have properly configured your router, and you are still experiencing these issues, our next suggestion is to bypass the router, and connect your device directly to your modem. Please ensure that you power down both the modem and the device for at least five minutes before attempting to connect to FINAL FANTASY XIV.

If you continue to receive these same errors when you are connected directly to the modem, then the problem lies with your ISP. We would recommend contacting them and advising them that one or more of the ports previously provided to you are being blocked or filtered, and that you do need access on these ports.

If you feel you may be experiencing packet loss while playing FFXIV, we kindly ask that you submit a report through the "Providing information on packet loss and lag" section at the bottom of our support form
