подключение java к БД c ssh-туннелированием

Есть БД с ssh-tunneling.

Через SQLyog и через DataTable в IdeaIJ к этой БД нормально подключаюсь. И мне нужно подключиться и выполнять запросы через java шатко-валко написала такой код:

Connection con = null;
JSch jsch = new JSch();
Session session = jsch.getSession(proxyUser, proxyHost, 22);
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.setPassword(proxyPassword);
session.setConfig("PreferredAuthentications", "publickey,keyboard-interactive,password");
session.connect();
session.setPortForwardingL(localPort, url, 3306);

Properties properties = new Properties();
properties.setProperty("user", user);
properties.setProperty("password", password);
properties.setProperty("useUnicode", "true");
properties.setProperty("characterEncoding", "UTF-8");
Class.forName("com.mysql.jdbc.Driver").newInstance();
con = DriverManager.getConnection(
        "jdbc:mysql://" + url + ":" + localPort + "/" + nameBD + "?autoReconnect=true", properties); 

и вот на последней строчке ошибка:

Could not create connection to database server. Attempted reconnect 3 times. Giving up

Подскажите, пожалуйста, как такую проблему можно решить?
