My WebProxy is built in node. I am using request module to fetch content from given Url. I am getting CERT_HAS_EXPIRED error for https://www.macu.com while the site opens fine in browser.

My Investigations

I investigated and checked the certificate details via Chrome but I see that certificate is not expired. I do not understand the issue with this website's certificate.

I thought this could be an issue with the vendor not present in the list of Node.js. I tried upgrading npm and node versions but no success. Moreover https://www.facebook.com's certificate is also issued by DigiCert High Assurance CA-3 vendor which clearly says that this vendor is present in Node.js CA list.

Here is the code:

var request = require('request');

function getContent(urlOptions) {
  request.get(urlOptions, function(error, response, body) {
    if (error) console.log('Error:'  + error);

    if (body) {
      console.log('Body:' + body);
    }
  });
}

exports.init = function() {
  var urlOptions = {
    headers: {
      'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8',
      'Accept-Encoding': 'gzip,deflate,sdch',
      'Accept-Language': 'en-US,en;q=0.8',
      'Cache-Control': 'max-age=0',
      'Connection': 'keep-alive',
      'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.152 Safari/537.36'
    },
    secureProtocol: 'TLSv1_method'
  };

  /* URL options for macu.com domain */
  urlOptions.url = 'https://www.macu.com/mystyle-checking';
  urlOptions.headers.host = urlOptions.headers.Host = 'www.macu.com';
  // urlOptions.rejectUnauthorized = false;  // Works when this option is set but it may cause security issue

  getContent(urlOptions);

  urlOptions.url = 'https://www.facebook.com';
  urlOptions.headers.host = urlOptions.headers.Host = 'www.facebook.com';

  getContent(urlOptions);
};

I just want to know

1. Why Request module complains for macu.com but not for facebook.com while both have certificates by same vendor.
2. What is the issue with macu's certificate ?
3. Why certificate is throwing error for node but is accepted by browser.
