FFXIV Error Codes 2002, 3001, and 4004 Explained

Due to things like congestion and the Endwalker launch, a number of Final Fantasy XIV errors are happening. To help people understand what’s going on, Director and Producer Naoki Yoshida offered details about three of them. The official explanations go over why FFXIV error codes 2002, 3001, and 4004 come up and how Square Enix’s team is dealing with them.

FFXIV error code 2002 is one that’s come up since Endwalker early access began. It comes up when over 17,000 people are waiting in a logical data center. (That’s the cap to stop login server outages.) It keeps people from lining up to log in. Yoshida says the new cap will be 21,000, thanks to backup development servers. Those servers will be deployed on December 7, 2021 when it is night time in Japan. (That means it could be happening around now.)

FFXIV error code 3001 happens when worlds exceed their login cap. When this happens, people in line get disconnected. Yoshida noted the Japanese Elemental data center’s Tonberry world is severely affected. He noted, “The Tonberry World has the largest number of login requests of all the game Worlds, and players are helping to mitigate this issue by using the World Visit System and logging into other Worlds. However, due to the way chat connections work when using the World Visit System, we cannot completely cut off a player’s connection with their character’s Home World, causing the total number of active connections to become enormous.” This results in error 3001 too. The fixes for these involve fixes that will start to be implemented in the December 8, 2021 world maintenance. The team also maximized network connection options for Tonberry.

Finally, FFXIV error code 4004 happens when people are waiting to log in, their turn comes up, but they don’t log in. This is due to something happening as part of a congestion measure. People aren’t being allowed in until 100 spaces in a world are free. When those 100 people’s turn comes up, 25 people could end up getting booted. Yoshida said that the team has a source code fix prepared, but aren’t sure if completely fixes it. So it is still working on it and will deploy it once the team is sure it fully fixed the issue.

Final Fantasy XIV and its Endwalker expansion are available for the PS4, PS5, and PC. FFXIV World maintenance will be held on December 8, 2021 for four hours.
