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

I understand that you feel that this is not a PSN issue, but I would still suggest contacting Playstation support as they may have some insight that I do not possess. Unfortunately, we are not sure what is causing this, so more information is always better. I do have some troubleshooting I'd like you to try as well:

1) Reset your router by turning it off for a few minutes, then back on.

2) Preferably, use a wired Ethernet connection as opposed to wireless.

3) Make sure that "Cookies" and "JavaScript" are ENABLED on the PSN Browser. This can be done by going to the web browser on the PS4, press the options button, then go to settings. The options for Cookies and Javascript will most likely be checked, uncheck them and then recheck them.

4) Restore the licenses on your PS4. Go to Settings > Account Management, and select Restore Licenses.

5) You can also try rebuilding your PS4's database. Boot the PS4 in safe mode. When the PS4 is off, press and hold the power button. Release it after you've heard two beeps: one when you first press, and another 7 seconds later. You should see a menu. Here, select 'Rebuild Database' (Make sure not to select 'Initialize') and follow the steps. I should note that this may some time depending on how much of your hard drive is used.

6) 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

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