Traditional XMPP doesn't use HTTP

传统的XMPP不使用HTTP

You can't connect to http://54.254.220.129:5280/admin (this is for browsers!)

您无法连接到http://54.254.220.129:5280/admin（这适用于浏览器！）

You need to use just the IP address

您只需要使用IP地址

public static final String HOST = "54.254.220.129";

#2

In your HOST string you already wrote the port number. So i think you need to write only ip address without port and admin like http://54.254.220.129. - After that try to connect. And try to login.

在您的HOST字符串中，您已经编写了端口号。所以我认为你只需要编写没有端口的ip地址和管理员，如http://54.254.220.129。 - 之后尝试连接。并尝试登录。

Try this;

尝试这个;

public static final String HOST = "http://54.254.220.129";
public static final int PORT = 5222;
public static final String SERVICE = "localhost";
public static final String USERNAME = "admin@localhost";
public static final String PASSWORD = "########";

ConnectionConfiguration connConfig = new ConnectionConfiguration(HOST, PORT, SERVICE);
XMPPConnection connection = new XMPPConnection(connConfig);

connection.connect();
connection.login(USERNAME, PASSWORD);
