Connect to the Server¶

Server details¶


Server IP	`15.204.112.102`
Data port	`54230`
Auth port	`54231`
View port	`54001`

Windower¶

Windower 4 has no "Login Server" field for private servers. Instead, you point a profile at xiloader.exe (the FJB loader) and pass the server address and ports as launch arguments.

Make sure xiloader.exe is in your FFXI folder, next to pol.exe (usually …\SquareEnix\PlayOnlineViewer\). See Get the loader.
Open the Windower 4 launcher and create or edit a profile.
Set Executable to xiloader.exe (use the full path if Windower can't find it).

Set Arguments to:

--server 15.204.112.102 --dataport 54230 --authport 54231 --viewport 54001

Save and launch.

Prefer to edit Windower4/settings/settings.xml by hand? The profile looks like this:

<profile name="FJBRelaunch">
  <executable>xiloader.exe</executable>
  <args>--server 15.204.112.102 --dataport 54230 --authport 54231 --viewport 54001</args>
</profile>

Skip the login prompt

Add your credentials to log in automatically:

--server 15.204.112.102 --dataport 54230 --authport 54231 --viewport 54001 --user YOURNAME --pass YOURPASSWORD

Ashita¶

Open the Ashita launcher.
Select your profile (or create a new one) and click Edit.
Under Login Server, enter 15.204.112.102.
Set the Data port to 54230, Auth port to 54231, and View port to 54001.
Save the profile and launch.

Tip

If Ashita uses a boot.ini or boot script, set --server 15.204.112.102 --dataport 54230 --authport 54231 --viewport 54001.

Troubleshooting¶

"Unable to connect" / connection timeout : Verify all four values (IP + 3 ports) match the table above. If the server was just restarted, wait 30 seconds and try again.

"Version mismatch" error : Your client needs to be the current retail version. Run the PlayOnline updater to patch up, then try again.

Stuck on the login screen / no response : Check the Discord #server-status channel — the server may be down for maintenance.
