Bootloader Problems

🔹 "Closing..." in red text before the bootloader closes, but after "Sending ID":

This is usually caused by a resolution, registry, or other configuration issue. Please verify your resolutions are compatible with your monitor and are the values you wish to use, and your window mode (fullscreen/windowed/borderless window) is what you want. Make sure all elements (directplay and vs redists) were installed correctly during launcher install.

If you’re not using the launcher, verify all registry values are correct (for example if you installed or uninstalled another ffxi client without a switch.bat you would see this).

🔹 "Failed to connect to server" followed by “Closing…” in red text:

if login server isn’t entirely down, see POL-3100/3101. Also, if all steps are followed and still seeing this every attempt while login isn’t struggling, you can try to reinstall the launcher.

🔹 The bootloader (ashita-cli.exe) will not launch when you press play on the launcher. This can happen on Windows 11 (Thank you @Arduin)

1. Open the Terminal App in Windows (NOTE: ensure you have the latest version of the Terminal App by updating it using the Microsoft Store app [Library->Get Updates] ) 2. Right-click on the Terminal window title bar, then click Settings 3. Change default profile to Command Prompt 4. Change default terminal application to Windows Console Host 5. Click Save, the game should now launch properly from the launcher
