Got "EAGAIN" error when sending request with "request module" (node.js module)

I have the same code for my Windows and Linux. It works on Windows but failed with my Linux.

Code:

  request({url:target_url}, // ANY URL WILL FAIL
    function (err, response, body) {
      console.log(err);

Out put error for this in my console:

{ [Error: connect EAGAIN] code: 'EAGAIN', errno: 'EAGAIN', syscall: 'connect' }

I guess this is not an issue with the request module but i don't know where to get help. Thanks for any kind of tips!
