Daphne does not handle wss requests

Hi.

Before open a bug, could you please tell me if my setup is ok?

Daphne 1.0.3
channels 1.0.3

routing.py
channel_routing = [
    route("websocket.connect", ws_connect, path=r"^/ws/chat/$"),
    route("websocket.connect", ws_connect_updates, path=r"^/ws/updates/$"),
    route("websocket.receive", ws_message_updates, path=r"^/ws/updates/$"),
    route("websocket.disconnect", ws_disconnect),
    route("http.request", http_ping, path=r"^/ping$", method=r"^GET$"),
]


channels worker started with:
manage.py runworker -v2

daphne started with:
daphne -e ssl:8003:privateKey=/etc/haproxy/keyring/spy.key:certKey=/etc/haproxy/keyring/spy.cert -v2 spywebsockets.asgi:channel_layer

No load balancer between client and sevrer (it's a dev env)

Client:
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>WebSocket Client</title>
</head>
<body>

<script src="jquery.js"></script>
<script src="reconnecting-websocket.js"></script>
<script>
    $(function () {
        var wsUrl = "wss://127.0.0.1:8003/ws/updates/";
        console.log("Connecting to " + wsUrl);
        var socket = new ReconnectingWebSocket(wsUrl);
    });
</script>
</body>
</html>

Error in firefox console:
11:54:03.682 Connecting to wss://127.0.0.1:8003/ws/updates/  websocket_client.html:14:9
11:54:05.686 Firefox can't establish a connection to the server at wss://127.0.0.1:8003/ws/updates/.  reconnecting-websocket.js:213:17
11:54:05.687 The connection to wss://127.0.0.1:8003/ws/updates/ was interrupted while the page was loading.

Logs in daphne console:

It seems that daphne never handles the connection. If I restart daphne on the same port, but without ssl and change from wss to ws, all is fine (so no firewall issue)

Thanks,
Giovanni
