Error 90006 on PS5

I’m trying to solve this issue since the Endwalker release. I get constant error 90006 on ps5, I have changed my lan cable, opened the ports, contacted my isp. Is there any way to solve this?

Good morning and thank you for posting in the Final Fantasy XIV Technical 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 PlayStation, 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. 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].
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 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.
