Ich kann keine Verbindung zur Datenbank herstellen, aber ich weiß nicht warum, da der Benutzername und das Kennwort korrekt sind und ich lokal über phpmyadmin eine Verbindung herstellen kann.

  Class.forName("com.mysql.jdbc.Driver");
  // Setup the connection with the DB
  connect = DriverManager.getConnection(
            "jdbc:mysql://localhost/yerobot", "yerobot", "yerobot123");

  preparedStatement = connect.prepareStatement("select * from userdata");

  resultSet = preparedStatement.executeQuery();
  while(resultSet.next()){
    // do read rs
  }

Immer wenn ich nach einer Verbindung rufe, erhalte ich diesen Stacktrace:
