Error ERR_CONNECTION_RESET when trying to consume webservice

I'm trying to consume in PHP a method of a web-service and when trying to open the page does not respond, I made the same request for SoapUI and the return comes quietly.

$client  = new SoapClient('http://localhost/cgi-bin/agws.exe/wsdl/IAG');
    $arguments = array(
                    "CRE_Codigo" => "20180301915",
                    "SequencialVencimento" => 1,
                    "Sequencial" => 0,
                    "Data" =>  "2018-06-03-06:00",
                    "Valor"=> 116309.12,
                    "LAN_ContaFinanceira" => "0001",
                    "ExportaAC" => 1
                );

No SoapUI:

$result = $client->__soapCall("IncluiBaixaContasReceber",array('BaixaContasaReceber' => $arguments));
