为什么在启动Daphne for prod / IIS时会出现错误?

我在SSE和Channels上使用Django eventstream(我不能使用Memurai或Redis)。当我运行本地服务器时,一切都运行得很好。用户可以提交一个文件,该信息将通过它调用的外部第三方API运行,真实的信息将从/events/ URL API显示回浏览器。
当通过IIS进行配置时,除了/events/ URL不可访问(404)之外,一切都工作得很好,因此SSE连接不会启动,这会停止其轨道中的一切。
使用命令:python manage.py运行服务器IP:端口

Django version 3.2.7, using settings 'mysite.settings'
Starting ASGI/Channels version 3.0.4

WebApp仅为本地网络托管。
现在,使用Daphne进行prod时,我会收到各种错误:

daphne mysite.asgi:应用程序:

所以我尝试使用daphne settings.configure()

C:\inetpub\wwwroot\mysite>daphne settings.configure()

import django
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings')
django.setup()
