TLS Error: socket hang up in nodejs - node.js

Question

I'am trying to connect on a server using tls in nodejs. Here is my code :
var options = {
rejectUnauthorized: false //self signed certificate
};
co = require("tls").connect(5200, "my_host", options, function(){
co.on("data", function(data) {
//do domething
})
}
This is simplified code. If I catch the error event, I have a ECONNRESET error, if I don't, I've got this trace :
Error: socket hang up
at SecurePair.error (tls.js:1001:23)
at EncryptedStream.CryptoStream._done (tls.js:697:22)
at EncryptedStream.read [as _read] (tls.js:493:12)
at EncryptedStream.Readable.read (_stream_readable.js:320:10)

at finishMaybe (_stream_writable.js:354:12)
at endWritable (_stream_writable.js:361:3)
at CleartextStream.Writable.end (_stream_writable.js:339:5)
If I connect directly to my server using openssl s_client -connect my_host:5200 it works great. Strange thing, with node version 0.10.*, it works on ubuntu 10.04, but not on my mac neither on ubuntu 12.04. My server is also a nodejs program running ubuntu 10.04. Not sure if all of this is related but any help would be great !
Cheers

Depending on what your client/server are doing, there may be a timing issue here. You want to set your event-handlers outside the callback to ensure they are setup before data is flowing. Try this:
var options = {
rejectUnauthorized: false //self signed certificate
};
co = require("tls").connect(5200, "my_host", options, function(){
//do something
});
co.on("data", function(data) {
//do something
});
