EPP服务器不响应EPP HELLO

我需要.NL登记处的工作 - sidn.nl - 通过他们的EPP API。我使用标准EPP HELLO，添加4个字节的消息大小（大端），调用CURL - 无标题，无数据返回。代码：EPP服务器不响应EPP HELLO

var epp_hello = '<?xml version="1.0" encoding="UTF-8" standalone="no"?>'+ 
    '<epp xmlns="urn:ietf:params:xml:ns:epp-1.0">'+ 
    ' <hello/>'+ 
    '</epp>'; // EPP HELLO 
var xml = bigEndian(epp_hello)+""; // big endian 
curl.setOpt(Curl.option.URL, "drs.domain-registry.nl"); 
curl.setOpt(Curl.option.PORT, 700); 
curl.setOpt(Curl.option.POST, 1); 
curl.setOpt(Curl.option.HEADER, true); 
curl.setOpt(Curl.option.POSTFIELDS, xml); 
curl.setOpt(Curl.option.HTTPHEADER , ['Content-type: text/xml']); 
curl.setOpt(Curl.option.TIMEOUT , 180); 
curl.setOpt(Curl.option.SSL_VERIFYPEER, true); 
curl.setOpt(Curl.option.SSL_VERIFYHOST, false); 
curl.perform();

我的IP在控制面板中被列入白名单。

为什么它不响应？它应该是EPP GREETING。他们的技术支持也没用，发过来链接到标准手动:-)

预先感谢任何帮助/咨询！

UPDATE：当通过TCP（而不是卷曲）调用的结果几乎是相同的：

var epp_hello = '<?xml version="1.0" encoding="UTF-8" standalone="no"?>'+ 
        '<epp xmlns="urn:ietf:params:xml:ns:epp-1.0"><hello/></epp>'; 
    var xml = bigEndian(epp_hello); 
    var ddd = new Date(); 

    var client = new net.Socket(); 
    client.connect(700, "drs.domain-registry.nl", function(xxml) { 
     console.log('Connected ' + ddd.toUTCString(),xxml); 
     client.write(xxml); 
    }.bind(null,xml)); 

    client.on('data', function(data) { 
     console.log('Received: ' + data); 
     client.destroy(); 
    }); 

    client.on('close', function() { 
     console.log('Connection closed'); 
    });

传出请求：

服务器返回的数据，连接被在第二秒关闭

使用tls代替网络解决：

const epp_hello = '<?xml version="1.0" encoding="UTF-8" standalone="no"?>'+ 
       '<epp xmlns="urn:ietf:params:xml:ns:epp-1.0"><hello/></epp>'; 

const opts = { 
}; 
var xml = bigEndian(epp_hello); 
var client = tls.connect(700, "drs.domain-registry.nl", opts, function(xxml) { 
    client.write(xxml); 
}.bind(null,xml)); 

client.on('data', function(data) { 
    console.log('Received: ' + data); 
});
