Frequently Asked Questions

What does FFXIV error code 90002 mean?
Error code 90002 in Final Fantasy XIV means the game client has lost its connection to the Square Enix game servers. It can be caused by network instability on your end, ISP routing issues, firewall blocks, or temporary server-side problems at Square Enix.
Is FFXIV error 90002 a server issue or my internet?
It can be either. First check the official FFXIV Lodestone server status page or the @FF_XIV_EN Twitter account to rule out a server outage. If servers are confirmed online and other players are connecting without issues, the problem is likely on your local network or ISP routing.
Why do I keep getting error 90002 mid-game?
Repeated mid-session 90002 errors usually indicate an unstable internet connection, packet loss, or Wi-Fi signal drops. Try switching to a wired Ethernet connection, restarting your router, and forwarding the required FFXIV ports on your router. Interference from VPNs or firewalls can also cause recurring disconnections.
Does error 90002 cause me to lose progress in FFXIV?
FFXIV saves your character's progress server-side, so you will not lose most progress. However, if you were in the middle of a duty, raid, or instanced content when the error occurred, you may receive a duty penalty for disconnecting. Cutscene progress and some unsaved instance progress may also be lost.
How do I fix FFXIV error 90002 on PS4 or PS5?
On PlayStation, go to Settings > Network > Set Up Internet Connection and switch from Wi-Fi to a wired LAN connection if possible. You can also try changing your DNS settings to Google DNS (8.8.8.8 / 8.8.4.4) within the network setup. Make sure your PlayStation Network connection is stable and that your router firewall is not blocking FFXIV traffic on the required ports.
