Solutions

This is a general login connection error. If you receive it once or twice, it’s not abnormal during login server congestion. If you can’t log in for longer than 10 minutes, there are a couple steps to isolate network or client issues.

1) Make sure you have the latest launcher version (Currently 1.1.4) and that you're running it as admin
2) “ipconfig /release” and “ipconfig /renew” in your command prompt (only if you’re comfortable doing so)
3) “ipconfig /flushdns” (Same, only if comfortable.)
4) reboot your pc
5) reboot your router

Feel free to attempt to log in in between each step, as the best thing to do when the login server is congested is to continue trying at 5 minute intervals.

Notes: If you’re on a mobile hotspot or hotel WiFi, this may cause problems connecting. Many hotels filter out FFXI’s network traffic. A VPN will likely fix that difficulty.

Important: If you're seeing this at character select, when you choose Character Select, or it consistently happens in the same place in a zone or cutscene, it's potentially not a network issue. Do the above steps first, then see the next post, "3101 Post Character Select"

You are disconnecting whilst in-game and receiving this code. You may also find that it is limited to certain zones only.

If none of the above solutions work try renaming your "USER" folder to "USER_backup". Caution: before doing this be aware that this will likely delete all of your macros so ensure you have attempted all other potential fixes first.

The user folder can be found via Horizon > Squae Enix > FFXI > USER.
