我可以看到您在CHANNEL_LAYER配置中硬编码了REDIS_URL。
如果您使用的REDIS示例来自heroku加载项，最好从环境变量访问它。您可能希望这样做，因为heroku加载项的凭据经常会更改。
阅读此Heroku文档，了解如何更改here附加组件凭据
值得一提的是，在外部存储凭据也是一个很好的做法。这样做，你就遵循了十二因素应用程序方法论。
此外，事实上，你是在http上运行并没有导致这个问题，因为你管理，以及通过使用'ws'协议时，运行http（参考三元运算符在设置您的WebSocket连接）。

根据@FAYEMI BOLUWATIFE的回答，我改变了我的通道层，它的工作！

CHANNEL_LAYERS = {
    "default": {
         'BACKEND': 'channels_redis.core.RedisChannelLayer',
        "CONFIG": {
            "hosts": [os.environ.get('REDIS_URL')]
        },

    },
}
