Error connecting WS client to server via HTTPS?

Question

Node.js

In general, a node throws this error when a client connects to a server:

Error: UNABLE_TO_VERIFY_LEAF_SIGNATURE

os: win7
node: 0.10.2

On the 8th node, everything works without problems, but there is no way to switch to the 8th node. free certificates issued by comodo.
Here are the listings, if necessary (more precisely, these are just examples from the documentation, I just indicated the path to the root certificates)

Server:

(function(){<br>
<br>
    "use strict";<br>
<br>
    var fs = require('fs');<br>
<br>
    // you'll probably load configuration from config<br>
    var cfg = {<br>
        ssl: true,<br>
        port: 8080,<br>
        ssl_key: 'crt/server1.key',<br>
        ssl_cert: 'crt/server1.crt'<br>
    };<br>
<br>
    var httpServ = require('https') <br>
    var cas = [fs.readFileSync('crt/COMODOHigh-AssuranceSecureServerCA.crt'), <br>
    fs.readFileSync('crt/AddTrustExternalCARoot.crt')]<br>
    httpServ.globalAgent.options.ca = cas;<br>
    console.log(httpServ.globalAgent.options)<br>
    var WebSocketServer   = require('ws').Server;<br>
<br>
    var app      = null;<br>
<br>
    // dummy request processing<br>
    var processRequest = function( req, res ) {<br>
<br>
        res.writeHead(200);<br>
        res.end("All glory to WebSockets!\n");<br>
    };<br>
<br>
    if ( cfg.ssl ) {<br>
<br>
        app = httpServ.createServer({<br>
<br>
            // providing server with  SSL key/cert<br>
            key: fs.readFileSync( cfg.ssl_key ),<br>
            cert: fs.readFileSync( cfg.ssl_cert ),<br>
            requestCert: true,<br>
            rejectUnauthorized: false<br>
<br>
        }, processRequest ).listen( cfg.port );<br>
<br>
    } else {<br>
<br>
        app = httpServ.createServer( processRequest ).listen( cfg.port );<br>
    }<br>
<br>
    // passing or reference to web server so WS would knew port and SSL capabilities<br>
    var wss = new WebSocketServer( { server: app } );<br>
<br>
    wss.on( 'connection', function ( wsConnect ) {<br>
<br>
        wsConnect.on( 'message', function ( message ) {<br>
<br>
            console.log( message );<br>
<br>
        });<br>
<br>
    });<br>
<br>
}());<br>

Customer

var WebSocket = require('ws');<br>
var ws = new WebSocket('wss://localhost:8080');<br>
ws.on('open', function() {<br>
    ws.send('something');<br>
});<br>

I ask for your help!
