Hello everyone.

Over the last several months, many of you have experienced lag or latency issues during peak times while connecting to the North American Data Center. In response to this, we have worked with Square Enix Japan in order to investigate the cause of the issue. We would like to thank all of you for the invaluable information you provided during our investigation. Fortunately, we found no issue with the Data Center itself. However, as many of you have discovered, the issue stems from routing congestion to the Data Center. As Square Enix only has control over the Data Center itself, we cannot affect any individual connection route.

In the case that you are receiving similar errors to the ones described in this sticky thread, we recommend first doing some standard troubleshooting as listed below. This is a list of common solutions that have helped many players in the past with standard connection issues.

-Clearing the browsing history, cookies and cache in Internet Explorer (even if this is not your primary web browser). Do the same for the PS4 internet browser if on PlayStation 4.
-Resetting your router by turning it off and leaving it off for a few minutes, then turning it back on.
-Connecting your PC/Mac/PS4 directly into the modem with an Ethernet cable
-Making exceptions for or temporarily disabling your firewall and/or anti-virus software
-Opening the following TCP ports on your router/hybrid modem
54992 through 54994
55006 through 55007
55021 through 55040
*For instructions on how to set up port forwarding, please contact your router manufacturer or Internet Service Provider (if your router was supplied by them).

If you have tried the suggested troubleshooting and still experience the same issues, we recommend contacting your Internet Service Provider and reporting the issue to them.

We sincerely apologize for any trouble or inconvenience this may cause you and hope you can continue to enjoy Final Fantasy XIV.
