node.jsから、Aerospike接続について

node.jsでAerospikeへの接続を試みています。
MacOS(El capitan)では正常に読み込み書き込みを確認できています。

Amazon EC2上では以下の様なエラーがでて動作しません。
エラー位置はAerospike接続したあとの、kinesis接続の箇所ですが、
エラーメッセージの内容はAerospikeになっています。

接続をしているコードは以下のとおりです。

var aerospike = require('aerospike');
var config = require('../config/databases.json');
var Key = aerospike.Key;
var StartingSequenceNumber = null;

aws.config.update({
    region: config.aws.region,
    accessKeyId: config.aws.accessKeyId,
    secretAccessKey: config.aws.secretAccessKey
});

var kinesis = new aws.Kinesis({ region: config.aws.region });

aerospike.connect({ hosts: config.aerospike.host, policies: { timeout: config.aerospike.timeout } }, function(error, client) {
    if (error) throw error;

    var key = new Key(config.aerospike.namespace, config.aerospike.setname, "StartingSequenceNumber");

    client.put(key, { seq: "123456789" }, function(error) {
        if (error) console.log(error);
    });

    client.get(key, function (error, record) {
        if (error) throw error;
        console.log(record);

        kinesis.describeStream({ StreamName: config.kinesis.stream }, function(error, result) {
              if(error) throw error;
              console.log(result);
       });

    });
});
