asgi.py и wsgi.py по дефолту ничего не менял.

запускаю сервер в разработке:
python manager.py runserver

захожу на страницу и в логах сервера вижу это:

[07/Apr/2024 19:31:49] "GET / HTTP/1.1" 200 786
Not Found: /ws/random_numbers/
[07/Apr/2024 19:31:49] "GET /ws/random_numbers/ HTTP/1.1" 404 2294

почему вебсокет не работает???
