我使用gremlin-javascript模块来访问远程 gremlin 服务器。我在 app.js 中的代码：
var gremlin = require('gremlin-client');
var client = gremlin.createClient(8182, 'localhost');
var query = client.stream('g.V()');
query.on('data', function(result) {
console.log(result);
});
query.on('end', function() {
console.log("All results fetched");
});
这工作正常，所有查询都得到执行。但是当我用我的远程服务器地址 - cbtitan.cloudapp.net 替换“localhost”时，它会返回 ECONNREFUSED 错误。
我应该改变/做什么来连接到那个远程服务器？或者我应该更改该远程服务器中的任何配置吗？我被这个问题严重卡住了，请帮帮我。提前致谢。
