Can't establish connection between peers

[the.co...@gmail.com]

Hello, Im using the latest peerjs lib v.3.0.1. Im testing p2p connectivity on the same PC (host + guest vm running in virtualbox) and I have problems with establishing of connection for such an environment. Actually connection could not be established

Here is the code (cut) Im using:

/* create peer */
peer = new Peer(_id, config.p2p); //tried turn server on/off
peer.on('open', function(__id){
/* connect to peers */
_this._connect(peer_id);
});

/* handle incoming connections */
peer.on('connection' ,function(conn){
debug.log('p2p: new peer connected');
});
/* handle error */
peer.on('error' ,function(err){
debug.log('p2p: error opening connection ' + err);
});

/* connect to peer */
this._connect = function(_peerId){
var conn = peer.connect(_peerId, {
'reliable': false //tried reliable: false/true here
});
conn.on('open', function(){
conn.on('data', function(data){
_this.forward(data);
});
});
}

Both peers (guest B & host A machines) are created without problems. Then I try to establish the connection from A:

_connect("18b23a1b420ab7e46dedf503502b94aa2e41c1db95e4bacaabd63f5cc5f5d696")

in the console on B I see incoming connection:
> p2p: new peer connected

And after this an error occurs:
> p2p: error opening connection CreateAnswer failed.

Connection is present in the peer.connections (A & B) but open=false and I cant send any data at all.

This is very annoying issue and I have no idea what to do with it. What's the most interesting - everything works perfect with peerjs v.0.2.8. Is it a bug, or?

And one small notice: clients with peers 0.2.8 & 3.0.x cant connect to each other

Please help me on this. Thank you

Are you able to connect two peers with our chat demo?

I dont think so. When connecting from A to B situation is next:
* B shows new connection "Chat with heokkpzfmjthuxr"
* A still shows "You have not yet made any connections."
Sending a message from B to A results in nothing

And when I try to connect from B to A - A crashes (chrome crash page) (but maybe thats not supported by code)

A is running 31.0.1650.26 beta-m
B is running 30.0.1599.101 m

Just switched to 0.2.8 branch and tried to connect from host to guest, everything works perfect

Cool, will look into it. My guess is that some of the configurations
we're using for Media connections don't play nicely with Chrome 31.

After switching to stable channel - it worked. Anyway please take care about v.31 which will be released quite soon. Thank you
