Bosh connection stream does not continue, with Strophe and Ejabberd

var Iniciar = {
    user: '[email protected]',
    pass: 'user1',
    conexion: null,...
}

$(document).ready(function () {
    Iniciar.log('Iniciando conexion');
    $(document).trigger('conectar');
});

$(document).bind('conectar', function () {
    //conexion
    var conn = new Strophe.Connection('http://192.168.0.1:5280/bosh');
    Iniciar.conexion = conn;
    Iniciar.conexion.rawInput = Iniciar.raw_entrada;
    Iniciar.conexion.rawOutput = Iniciar.raw_salida;
    Iniciar.conexion.addHandler(Iniciar.on_presence, null, "presence");

    Iniciar.conexion.connect(
                    Iniciar.user, 
                    Iniciar.pass,
                    function(status){
                        if(status == Strophe.Status.CONNECTING){ ...else if(status == Strophe.Status.CONNECTED){
                        $('#cuadro').append(' 2 de 3 conectado ');
                        $(document).trigger('conectando');
                    }else{
                        //
                    }
                }
);

The previous code allows me to enter only once, then I close section. To later enter again but do not enter and the log unfolds me the message. and so on I have to restart the server to enter once ... I am using Ejabberd 18.06 on windows server2008 I have congured in IIS and the server is installed on a local network.
