Websocket connection by HTTPS with Let’s Encrypt about daphne HOT 6 CLOSED

It looks fine to me at first glance - and if Firefox connects it means websocket is getting through alright. What error do you get from the other browsers?

from daphne.

I forgot to say that a successful connection I get by means of little hack in my routing.py:

def ws_connect(message, pk):
    logger.info("WS: connected new user with pk={}".format(pk))
    try:
        user = User.objects.get(pk=pk)
        if not user.is_authenticated():
            logger.warn("WS: user pk={} is not authenticated".format(pk))
            return  # using /stream/ (devices) only for authenticated users
        Group(user.group_name).add(message.reply_channel)

        # FIXME: little hack, send a message for connection establishment
        group = Group(user.group_name)
        group.send({
                "text": json.dumps({
                        'payload': {
                            'action': 'connection',
                            'data': {}
                        }
                    }
                ),
        })
    except ObjectDoesNotExist:
        logger.warn("WS: user for pk={} not found".format(pk))
    except Exception as ex:
        logger.error(ex)

Without sending of the empty message the connection does not established and in Firefox too.
Without sending the message I get records in the log about that the client has been connected but immediately there are disconnection of the websocket client and I have messages in my browser:

WebSocket connection to 'wss://my.domain.net:8443/4/stream/' failed: WebSocket is closed before the connection is established.

and after a few attempt:

reconnecting-websocket.min.js:1 WebSocket connection to 'wss://my.domain.net:8443/4/stream/' failed: Error in connection establishment: net::ERR_TIMED_OUT

Ah, it's because you're not accepting the connection like 1.0 now requires! See http://channels.readthedocs.io/en/latest/releases/1.0.0.html#connect-consumers

Thanks for your hint! I'll try it soon.

Closing due to lack of response.

Hi

I am experiencing a very similar issue to zeezdev. My setup is almost identical, besides me using Apache instead of nginx. I keep getting "WebSocket is closed before the connection is established." warnings followed by a "WebSocket opening handshake timed out" error after the web socket not being able to connect. Is there a suggested fix for this? I am running daphne with letsencrypt certificates in much the same was as described by zeezdev.
