Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

I apologize for not getting to your other thread sooner.

As for your issue, it sounds like you are running into some sort of congestion along your route to the server, especially since this happens at peak hours. Unfortunately, you don't have much control over anything beyond your own network. Because of this, I'd suggest trying some of the following to reduce any connection issues within your own network:

1)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"

2)Make sure your anti-virus/firewall has the appropriate exceptions for Final Fantasy XIV.

3)You might want to 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

4)Change DNS to 8.8.8.8 or 1.1.1.1
- Go to the Control Panel
- Click Network and Internet > Network and Sharing Center > Change adapter settings
- Right-click on the connection you are using and select Properties
- Under the Networking tab you will see a long list of available options
- Scroll down and doubleclick on Internet Protocol Version 4 (TCP/IPv4)
- Select 'Use the following DNS server addresses'

5) You can also try a clean boot. Simply open the task manager and select the 'Start up' tab. Disable everything here and restart the PC.

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