The FFXIV 90002 error is a connection-related issue that causes a player to be disconnected from the game, often due to packet loss or corrupted files.

To fix it, you can try restarting your modem/router, using a different internet connection like a mobile hotspot, checking your firewall and antivirus settings, and reinstalling the game if corruption is suspected.

Here’s a breakdown of what the error means and how to troubleshoot it.

What Does the FFXIV 90002 Error Mean?

How to Fix FFXIV Error 90002

1. Check for Server Issues or Maintenance

• Square Enix’s Official Server Status: Go to the official FFXIV Server Status page or check the FFXIV Twitter for any ongoing maintenance or server outages. Sometimes, the 90002 error occurs if the servers are under maintenance or experiencing issues.

• Reddit or Forums: Check forums like r/ffxiv for real-time reports from players to see if others are facing the same issue.

2. Check Your Internet Connection

• Run a speed test: Use websites like Speedtest.net to check your connection. Ensure you have stable download and upload speeds.

• Restart your router/modem: This can resolve many connection issues, especially if you’ve been online for a while and your router needs a fresh start.

• Use a wired connection (Ethernet): If you’re on Wi-Fi, try switching to a wired connection to reduce the risk of packet loss or signal interference.

• Ping Test: Try pinging the FFXIV servers to check for network lag:

  • Open Command Prompt or Terminal and type:

    ping ffxiv.com


    Look for unusually high ping or packet loss.

3. Flush DNS Cache

Sometimes DNS issues can cause connection problems. To flush the DNS cache:

• On Windows:

  • Press Windows key + R to open the Run window.

  • Type cmd and press Enter.

  • In the command prompt, type:

    ipconfig /flushdns


• On macOS:

  • Open Terminal and type:

    sudo killall -HUP mDNSResponder


  • Press Enter and restart your system.

4. Disable Firewall and Antivirus Temporarily

Your firewall or antivirus software might block the connection to the FFXIV servers.

• Windows Firewall:

  • Go to Control Panel > System and Security > Windows Defender Firewall.

  • Click Allow an app or feature through Windows Firewall and ensure FFXIV is listed as allowed.

• If you use third-party antivirus, check their firewall settings and ensure that FFXIV is not being blocked.

5. Use a VPN (if your ISP is throttling)

• Try a VPN: Some ISPs throttle gaming traffic. Using a VPN might help you bypass any throttling. Choose a VPN with fast servers and low ping.

• Servers to try: If you’re in North America, try connecting to a U.S.-based VPN server. For Europe, use an EU-based server.

6. Try a Different Server (if possible)

• If your server is congested, try selecting a different one (if possible). For example, during high-traffic times, some servers can experience more lag or disconnects.

7. Restart FFXIV or Re-login

• Sometimes a simple restart of the game can fix the issue, especially if it’s a temporary issue with your client’s connection to the server.

• If you’re in the middle of a session, you may want to log out of FFXIV completely and try reconnecting after a few minutes.

8. Verify Game Files (if on Steam)

If you’re playing through Steam, verify the integrity of the game files:

• Right-click on Final Fantasy XIV in your Steam library.

• Select Properties > Local Files and click Verify Integrity of Game Files.

• This can help ensure that no game files are missing or corrupted.

9. Check for Modem/Router Settings

• Port Forwarding: In some cases, adjusting the router’s port forwarding settings can help. You’ll need to forward ports 55006-55007 to your PC for FFXIV to communicate properly with the servers.

• Change DNS Servers: Use public DNS servers like Google DNS (8.8.8.8, 8.8.4.4) or Cloudflare DNS (1.1.1.1) to help with connection stability.

When to Contact Support

• If none of the above fixes resolve the issue and you’re still getting the error code 90002 consistently, consider reaching out to Square Enix Support:

  • FFXIV Support Website

  • You can submit a ticket or use live chat for assistance with server-specific or account-related issues.
