无法连接到我的 Node.js 服务器

无法连接到我的 Node.js 服务器

我有一个 VPS（在 linode 上），我在上面安装了 Node.JS。

我的 server.js 文件如下：

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(1337);
console.log('Server running on port 1337');

当我在我的服务器上尝试这个时：

wget http://localhost:1337

它确实能工作并下载响应。但在外部，Google Chrome 却说“哎呀！Google Chrome 无法连接到 xxx.xxx.xx.xx:1337”

这是 Iptables 的输出：

Chain fail2ban-ssh (1 references)
target     prot opt source               destination
RETURN     all  --  anywhere             anywhere

可能出了什么问题？谢谢！

尝试另一个端口。3000 应该可以工作。
