When to Call a Professional

If you have completed all troubleshooting steps and error 90006 persists only for your account on a network that works fine for other games or other FFXIV accounts, contact Square Enix Support directly at support.na.square-enix.com with your traceroute or WinMTR results. If the issue is confirmed to be ISP-side packet loss or poor routing, escalate with your Internet Service Provider and request that they investigate routing to Square Enix's server IP ranges. In rare cases, a network technician from your ISP may need to visit your home to check line quality.

Frequently Asked Questions

What does FFXIV Error Code 90006 mean?
Error Code 90006 in Final Fantasy XIV means the game client encountered a connection error during data transfer with Square Enix's servers. It indicates that the data being sent or received between your device and the game servers was interrupted, timed out, or blocked before it could complete successfully.
Why do I keep getting Error 90006 in FFXIV even with a good internet connection?
A fast internet connection does not always mean a stable one. Error 90006 is often caused by packet loss, poor routing between your ISP and Square Enix's data centers, firewall or antivirus interference, or NAT/port issues on your router — none of which are reflected in your general download speed. Try switching to a wired connection, flushing DNS, and checking your firewall settings even if your connection seems fine for other activities.
Does Error Code 90006 mean I am banned from FFXIV?
No. Error Code 90006 is a network connectivity error and is not related to account bans or suspensions. If your account had been suspended or banned, you would receive a different error code with a message referencing your account status. Error 90006 is purely a data transfer and connection issue.
Does a VPN fix FFXIV Error Code 90006?
It depends on the root cause. If your ISP has poor or congested routing to Square Enix's servers, a gaming-optimized VPN or proxy service (such as Mudfish, Exitlag, or WTFast) may help by providing a better network path. However, if a VPN is already running when you get the error, disabling it is one of the first things you should try, as it may be causing the connection problem.
Is Error 90006 a PlayStation-specific FFXIV error?
No. Error Code 90006 can occur on all platforms that support Final Fantasy XIV, including PC (Windows), PlayStation 4, and PlayStation 5. The troubleshooting steps differ slightly by platform — PC users can flush DNS and edit firewall rules, while PlayStation users should focus on network settings, NAT type, and router configuration.
