Apart from the servers or Square Enix issues, the following can be regarded as the main factors that may cause error 3001 for FFXIV Endwalker:
Perform a Cold Restart of the Router and System/ Console
A temporary communication glitch between your console/system and the game servers may result in the error 3001 on FFXIV Endwalker. In such a case, performing a cold restart of the router may clear the error 3001 as it will reset many internal components to the defaults and may acquire a new IP from the ISP (if a static public IP is not assigned). If restarting did not work, make sure that the ports required by the game are properly forwarded in the router’s settings, and then check if the issue is resolved.
Try Another Data Center of FFXIV
FFXIV Endwalker may show the error 3001 if the game’s data center you are trying to connect is overloaded and the server is actively refusing new connections. Here, you can fix error 3001 FFXIV by trying another data center.
Try Another Network or Use A VPN
You may encounter the error 3001 on FFXIV Endwalker if your ISP is restricting the traffic from your network to the FFXIV servers. In such a case, trying another network or using a VPN may clear the error 3001.
Delete or Rename the Characters Folders in the Installation Directory of FFXIV
If the character cache folders in the installation directory of FFXIV are corrupt, then that may lead to the error 3001 on FFXIV Endwalker, and deleting (or renaming, if you want to play safe) the characters folders in the installation directory of the game may solve the problem. Do not worry, these folders will be recreated on the next game launch but you may lose some customizations of the characters.
Reset the Router to the Factory Defaults
FFXIV Endwalker may show the error 3001 if the firmware of the router is corrupt and it is not letting the game access a resource essential for the game’s operation. Here, resetting the router to the factory defaults may clear the FFXIV error 3001. Before trying that, make sure to keep a note of the router’s configurations required to set up the router after factory resetting it. The exact instructions to reset the router might differ but the general guidelines are as under: If not, check if connecting the system or console directly to the Internet by removing the router solves the problem. If so, then the router’s incompatibility with the game is causing the issue and you may acquire a new router or modem from the ISP. If the issue reappears with the new router, then check if changing the router’s mac address (some models do have the functionality) and acquiring a new IP resolves the issue. If the issue persists, you may wait (close game and all related processes) for at least 24 hours (as the server cache resets after 24 hours) and then try if the error is cleared. If the issue continues to occur, then you may contact Square Enix to perform a route trace to check where the issue is occurring.
