    When I tried to run the Django application using sslserver as shown below,

    python manage.py runsslserver

    Errors:

    It's working fine with python manage.py runserver mand, means for http it's working but not with https.

    How to resolve this issue? (How to debug to sort out this issue?)

    Is there any other way to deploy WebSockets on https portal?

    Still facing this issue. Can anyone please help?

    Anyhow this is for testing purposes, finally, I need to deploy it on Apache2.4 in the windows server machine. Where I have already set up for https but not for web sockets.

    • 1 It says Not Found: /ws/home. Does it say the same for http? – ege Commented Nov 12, 2019 at 8:45
    • 2 No, it's working properly. There is no issue with http. – shaik moeed Commented Nov 12, 2019 at 8:46
    • 1 @shaikmoeed Please check if you configured CHANNEL_LAYERS in settings.py – wowkin2 Commented Dec 5, 2019 at 10:22
    • 1 @wowkin2 CHANNEL_LAYERS was configured and it's working totally fine with http. How to run on https? – shaik moeed Commented Dec 5, 2019 at 10:25
    • 2 @shaikmoeed have you tried to use Daphne for that? If not - really remend to do that: github./django/daphne – wowkin2 Commented Dec 5, 2019 at 13:15

    Reset to default 13

    I found the answer, the runserver mand correctly detects asgi.py file and run the Django channels application on WebSockets using daphne. Somehow runsslserver is not doing the same job, It's running the wsgi.py file instead of asgi.py file.

    After reading different approaches, I get to know that we can handle HTTPS request using our normal development server (i.e., using wsgi.py file) and wss request by using Daphne(i.e., using asgi.py file).

    Daphne was an officially designed server to handle django-channels(built on the top of the twisted module).

    So, finally, we need to run two servers to handle https and wss separately.

    # In mand prompt 1 (For production, use Apache or Nginx to serve HTTP requests)
python manage.py runsslserver 0.0.0.0:8000

# In mand prompt 2 (This works for production as well).
daphne -e ssl:8001:privateKey=cert\\private.pem:certKey=cert\\public.pem real_time_table.asgi:application

    We should use the same SSL certificates used by runsslserver for testing.

    Finally, in JavaScript:

    var loc = window.location;
var wsStart = 'ws://';
if (loc.protocol == 'https:') {
     wsStart = 'wss://'
}
// var endpoint = wsStart + 'your_ip_address:port_given_to_daphne_server' + '/ws/home';
// For above mand, it look like this
var endpoint = wsStart + 'xxx.xx.xx.xxx:8001' + '/ws/home';
// Note the websocket port is 8001
var socket = new WebSocket(endpoint);

    I hope, this will save someone's time.
