90002 errrrrrrrrrrrrooooooooooooorrrrrrrrrrrrr
I have played this game over 900 days. I didn't have this 90002 error until two days and it is making the game suck. I want to know what Square-enix is going to do about it?
as mentioned, its likely the router settings if you are getting constant boots
The PS4 isn't compatible with some router settings. Login to your router through the PC.
1. WPA-PSK/WPA2 > WPA-PSK
By default, many routers are set to both and WPA2 has priority by default when both are enabled. PS4 will not work with WPA2, thus causing the immediate boots (although PS3 oddly does work when set to both.
2. AES/TKIP > TKIP.
Set to TKIP only.
3. Port forward/trigger.
The PS4 should not be able to connect smoothly, but if not, you can attempt to include port forwarding. Don't have the port numbers at, though, but I think you won't need it.
Enjoy.
