Échec du chargement de la ressource: net::err INSECURE RESPONSE socket.io

je me connecte à un port sur mon serveur via ssl... récemment, J'ai commencé à ne pas charger l'erreur resource: net::ERR_INSECURE_RESPONSE sur chrome lors de la connexion à la node.js + socket.serveur io.Voici le code de configuration de mon serveur:

var fs = require('fs');
var express = require('express');
var routes = require('./routes');
var https = require('https');
var path = require('path');
var socketio = require('socket.io');
var util = require('util');
var url = require('url');
var privateKey  =  fs.readFileSync('ssl/keys/xxxxxxxxxxxxxxxxxxxxxxxx.key', 'utf8');
var certificate = fs.readFileSync('ssl/certs/xxxxxxxxxxxxxx.crt', 'utf8');
var credentials = {key: privateKey, cert: certificate};
var sizeOf = require('image-size');


var DBWrapper = require('node-dbi').DBWrapper; 
var DBExpr = require('node-dbi').DBExpr; 
var dbConnectionConfig = { host: 'localhost', user: 'user', password: 'password', database: 'dbname' };
dbWrapper = new DBWrapper( "pg", dbConnectionConfig );
dbWrapper.connect();

var app = express();

app.set('port', process.env.PORT || 8080);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(express.logger('dev'));
app.use(express.json());
app.use(express.urlencoded());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));

app.get('/', routes.index);


var server = https.createServer(credentials,app).listen(app.get('port'), function(){
  console.log("Express server listening on port with https " + app.get('port'));
});

 var io = socketio.listen(server);

Ce que je fais mal?

Modifier: C'est comment je me connecte sur le côté client:

socket = io.connect("https://website.com:8080", {'reconnect': false});
