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 on FINAL FANTASY XIV. Most of the time, it results from certain security/privacy changes on the PSN web browser which can be reset as follows:
- Select 'Settings' from the main menu and navigate to 'System'.
- Once there, click 'Web Browser'.
- To clear cookies, please select 'Delete Cookies'.
- To clear the browsing data, please select 'Clear Website Data'.
- Double check to see if JavaScript is enable by selecting the slider next to 'Enable JavaScript'.
The fault may also lie with the "Date & Time" settings on your PlayStation 5. We would advise to please follow the provided steps to adjust your console's clock to assure it is accurate and up-to-date:
1. Close the FINAL FANTASY XIV game/application.
2. Go to [Settings] on your PlayStation 5.
3. Select [System] > [Date and Time], and click X to select the automatic "Set via Internet" option. (Please do not manually set the date and time.)
4. Once, the date and time settings have been updated, please restart your PlayStation 5 console.
5. Once your console has fully restarted, please start the FINAL FANTASY XIV game/application.
6. Please make sure all other internet-enabled devices (including smartphones, laptop/desktop PCs, tablets, etc.) have been disabled and/or turned OFF to minimize game interference.
If the suggestions provided above do not resolve the issue, then there is a communication error. (Not the same as a connection error.)
Check the following Port Ranges on your router/modem to ensure that the following Port Ranges have been opened/forwarded/triggered:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040
*This can be done by visiting www.portforward.com, locate your specific Router/Modem Brand and Model Number from the 'List of Routers', and you will find a step-by-step guide on how to access your ports.
If you have properly configured your router, and you are still experiencing these issues, our next suggestion is to bypass the router, and connect your console directly to your modem. Please ensure that you power down both the modem and the console for at least five minutes before attempting to connect to FINAL FANTASY XIV.
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 your provider 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.
Lastly, we suggest power cycle the console and router by shutting down the PlayStation 5/Router and leaving the power supply unplugged for 5-10 minutes.
We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
