Check Server Status

The first step in troubleshooting this 90001 error is to check if there is a server issue and you’re not used to this kind of outage.

Fortunately, there is an easy way to check if there are any server issues currently affecting Final Fantasy XIV Online. Simply open your default browser and check the FFXIV server status page to see if there are any server issues in your area.

You can check the status of the server that is causing error 90001 by clicking on the data center that is connected to your region.

Run as Administrator is an option available when launching FFXIV. When launching it, make sure you select Run as Administrator under the Run As menu.

You are probably out of control of the problem if your server is showing partial service or maintenance. As a result, you must wait for the developers to fix the server problem or connect to another server while this error is being corrected.

Removing a third-party firewall

A third-party firewall that excludes or whitelists the game executable will result in a problem caused by overprotection. You will have to remove the firewall completely if you don’t know how.

The same security suites will still exist even after you disable your real-time protection if you are using a third-party AV + firewall.

  1. By pressing Windows + R, you will be able to open the Run dialog box.
  2. The Programs and Features menu will open when you type “appwiz.cpl” in the text box.
  3. The third-party firewall can be found on the list of installed applications in the Programs and Features menu.
  4. You can uninstall it by right-clicking it and choosing Uninstall.
  5. You’ll be prompted to uninstall the program, then restart it after you’ve completed the process.

Configure Network Interface Controller settings

A network card (Network Interface Controller) malfunction can also cause error 90001, causing the server connection to be interrupted.

In Final Fantasy XIV, this specific issue can occur with high-end network cards that use power-saving features when idle. It turns out that this can cause problems for the game.

  1. The “Run” dialog box will appear when you press Windows + R.
  2. Open the Device Manager by typing devmgmt.msc into the text box and pressing enter.
  3. Click on the drop-down menu and expand Network Adapters once you are in Device Manager.
  4. You can then select Update Driver from the pop-up menu that appears by right-clicking on the network adapter controller that is active.
  5. Wait until the first scan is complete, then select Automatically check for driver updates.
  6. You will be asked to follow the on-screen instructions to install the new network card driver if a newer version of the driver is found.
  7. To view the properties of a network card driver, right-click it again after it is installed.
  8. You can save power by unchecking the Allow computer to turn off this device.
