Thanks for your information! I just did all the configurations again following this post( http://masnun.rocks/2016/11/02/deploying-django-channels-using-daphne/). And I think it is extremely useful for me and my website is now running. And you are right, I don't need both uwsgi and daphne. Only daphne is sufficient.
