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

The issue you are describing is most associated with interference with the game data. Most of the time, it results from certain security/privacy changes on PSN web browser. Please 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.
