Click on the desired game server in the Game Server Manager.
Wait until the Game Server Manager has loaded completely. You will find a tab with the name “Files“. You will now find a button with the name “FTP Data” on the right side of the content.
A window will open showing you all the access data for the FTP server.
Please note: If you have previously installed an FTP server on your Linux server, the functionality of this method is not guaranteed.
