Error return php nusoap

Hello, I have configured a WebService server for a license, made in PHP nusoap, which was working properly, but due to problems with the internet provider we decided to host a third party in the new hosting when consuming the WS does not come back the return xml, but in the server it executes the service notifying in the DB the query

the WS code and php info are attached

Edit: I saved a txt with the output of file_get_contents ('php: // input'), and it was working fine

<?php
// cliente.php
include('assets/vendor/nusoap/lib/nusoap.php');

$cliente = new nusoap_client('http://ws.orionsistemas.com/licensing/index.php?wsdl');
$parametros = array('CNPJ'=>"12345678901234",'RazaoSocial'=>"razao social","1" ,"1");       
$resultado = $cliente->call('Verifica', $parametros);

echo $resultado;?>


<?php
// servidor.php
include('../assets/vendor/nusoap/lib/nusoap.php');


$servidor = new nusoap_server();


$servidor->configureWSDL('urn:ServerOrion');
$servidor->wsdl->schemaTargetNamespace = 'urn:ServerOrion';


function Verifica($CNPJ, $RazaoSocial,$Uso_Interno_5,$Uso_Interno_13){
        require_once '../assets/classes/licensing/empresa.class.php';
        require_once '../assets/classes/DB.class.php';
        $empresa = new empresa($CNPJ, $RazaoSocial, $Uso_Interno_5, $Uso_Interno_13);
        $empresa->notifica();
        return $empresa->toXml();
