I created a simple chat app using WebSockets after following the official Django-channels tutorial. However, I can't get it to work in production. I have done a few google searching to find out a forum in Pythonanywhere saying that they don't support WebSocket, I contacted the team and they told me the same thing. I have done even more google searching and found things related to Daphne server, Nginx, and a few other things I never heard about before.

As I'm new to Django-channels I'm currently very confused! Is there something I can do to make my WebSocket website run normally in Pythonanywhere on production (for free of course) Or I have to delete all of the WebSocket code and replace it with repetitive Http called to check of new messages (With AJAX)?

And if there is no other solution but to move to repetitive Http calls, is there any other web hosting service that offers free play which includes free SSL certification, the domain name (such as mydomain.servicename.com) instead of random characters, and WebSocket support?

Thanks

the code i use

I don't know if it was relevant, also it's working perfect in development so i don't think there is an error in it

settings.py:

INSTALLED_APPS = [
    'channels',
    ...
    'django_cleanup',
]

CHANNEL_LAYERS = {
    'default': {
        'BACKEND': 'channels_redis.core.RedisChannelLayer',
        'CONFIG': {
            "hosts": [('127.0.0.1', 6379)],
        },
    },
}

main routing.py (in route folder)
