我试图连接到jboss与jboss cli客户端在一些服务器，它的工作完美，但从外部的服务器，它显示的消息错误：

Failed to connect to the controller: The controller is not available at ip:9990: java.net.ConnectException: WFLYPRT0023: Could not connect to http-remoting://ip:9990. The connection timed out: WFLYPRT0023: Could not connect to http-remoting://ip:9990 Connection refused

我启动以下命令：
--连接--控制器=服务器Ip：9990 --用户=用户名Jboss--密码=密码Jboss
