nodejs https Error: socket hang up with localhost

Posted by: admin November 29, 2017 Leave a comment


I have this small code snippet that targets an endpoint hosted on localhost

var https = require('https');

var options = {
  hostname: 'localhost',
  port: 443,
  path: '/',
  method: 'GET',
  agent: false

var req = https.request(options, function(res) {
  console.log("statusCode: ", res.statusCode);
  console.log("headers: ", res.headers);
  res.on('data', function(d) {

req.on('error', function(e) {

and I always get the error:

{ [Error: socket hang up] code: ‘ECONNRESET’, sslError: undefined }

It seems that the request is not even received by the endpoint because the it’s not captured by it and there is no timeout happening.

If I try a request like https:// localhost from the browser, it’s sent successfully.

If I just change the host in the code to something like encrypted.google.com, it works successfully as well.

Anyone knows why this might happen ?

Edit: I’ve also tried adding the same headers sent by the browser like accept, user-agent .. etc, but still not working

Edit2: this is the stack trace that appeared when I logged it:

ECONNRESET means the TCP connection was closed unexpectedly, ie. somewhere mid protocol.

But the code you wrote seems OK to me.

Maybe you are running into this issue https://github.com/joyent/node/issues/5360

TL;DR: You could try with latest node version and secureOptions: constants.SSL_OP_NO_TLSv1_2 added to your options.

UPDATE SSLv3 is broken, https://access.redhat.com/articles/1232123 ; maybe ditch ISS?
