我有一个项目，我使用频道并且在本地一切运行良好，但是当我在 Heroku 上部署时，每次尝试连接时都会得到 403。起初我认为问题出在 Heroku 上，因为我在本地对其进行了测试，甚至在本地使用了 Heroku 的数据库和 redis 实例，一切正常。
但是，当我使用ngrok打开到我的本地主机的公共隧道时，我发现结果与 Heroku 中的相同。对于每个请求，我都会得到 403 并尝试调试它并没有多大帮助，因为事件循环有时会突然控制或出现超时错误。设置与一个在本地访问而另一个在远程访问的设置完全相同。这就是我开始达芙妮的方式：
daphne weout.asgi:application --port 8000 --bind 0.0.0.0 -v 3.
我的库版本：
- Django==2.0.7
- 频道==2.2.0
- 通道-redis==2.4.0
- 达芙妮==2.3.0
将 Daphne 的 versbosity 设置为最大值，这是我尝试连接时得到的结果：

我使用 Daphne 为我的普通 Django 视图和 websocket 消费者提供服务。一切都适用于 Django 视图，因此仅在连接到消费者时才会出现问题
有没有人在远程访问 Dapnhe 时遇到类似的问题？起初我尝试将 uvicorn 与 gunicorn 一起使用，但是当消费者在初始连接阶段关闭时它们会出现错误，所以我切换回 Daphne
