Urgent Help Needed – Error 10105 on PS4

Hi everyone,

I’m having trouble logging into Final Fantasy XIV Online on my PS4. I keep getting Error Code 10105, and I get stuck on the "Now Loading" screen, unable to proceed.

I’ve already tried the following:

- Restarting my router and modem
- Using a wired connection instead of Wi-Fi
- Checking if my internet is working properly
- Waiting for a while and trying again

Interestingly, I can switch data centers without any issues, but I still get stuck when trying to log in.
Has anyone else encountered this problem? Any help or suggestions would be greatly appreciated!

Thanks in advance.

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

We apologize for any inconvenience experienced when trying to play Final Fantasy XIV.

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.

The fault may also lie with the "Date & Time" settings on your PlayStation 4. We would advise to please follow the provided steps to adjust your console's clock to assure it is accurate and up-to-date:
Close the FINAL FANTASY XIV game/application.
Go to [SETTINGS] on your PS4.
Select [Date and Time], and "Set via Internet". (Please do not manually set the date and time.)
Once, the date and time settings have been updated, please restart your PlayStation 4 console.
Once your console has fully restarted, please start the FINAL FANTASY XIV game/application.
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.

Try power cycling the system by shutting down the game and turning off the system completely. Unplug all the wires from the back and hold the power button down for 10 seconds. After doing that, please plug everything back in and turn the PlayStation on. Once the system is on, please launch the game. Doing so will clear the cookies and the cache.

If the suggestions provided above do not resolve the error you are receiving, 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.
