我在一个 Angular 项目中工作，你想使用测试服务器连接到 Gaucamole，这是我的代码：
this.manager = new RemoteDesktopManager(tunnel)
const parameters = {
ip: '52.139.24.171',
port: 3389,
type: 'rdp',
image: 'image/png',
width: window.screen.width,
height: window.screen.height,
username: 'TestSavvyAdmin',
password: 'TestSavvyAdmin!4',
dpi :96
};
{address}&image=image/png&audio=audio/L16&dpi=96&width=n&height=n
this.manager.connect(parameters);
我的服务器正在运行，但是当我运行 jar 时，我无法连接到 guacd，并且出现以下错误：
C:\guacamole-test-server>java -jar target/gts.jar --guacd-host 1.2.3.4 --
guacd-port 4822 --port 8080

你知道我为什么会收到这个连接错误吗？
提前致谢。
