try using the on error event of the client to find the issue.
var http = require('http');
var options = {
host: 'google.com',
path: "https://stackoverflow.com/"
}
var request = http.request(options, function (res) {
var data="";
res.on('data', function (chunk) {
data += chunk;
});
res.on('end', function () {
console.log(data);
});
});
request.on('error', function (e) {
console.log(e.message);
});
request.end();
