Good morning! Thank you for posting in the Final Fantasy XIV Technical Support Forums.

Please try the following troubleshooting as it may help resolve your concern:

- Make sure your fire wall or antivirus program (Windows Defender, Avast, Norton, Malware Bytes, etc.) is not interfering with the game
- Change local DNS: Please try changing the local DNS server to 8.8.8.8 and 8.8.4.4
- 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.
- Power cycle the router/modem by shutting down the router and leaving the power supply unplugged for 5-10 minutes.

-Lastly, check to see if the following port ranges are opened on your router.
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

*You may learn how to do this by visiting http://www.portforward.com/
Find your specific router/modem's brand and model number from the 'List of Routers' and you will be provided a step-by-step guide on how to access these port settings.


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 again 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.

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