Daphne + Django Channels在Heroku上给出了503的错误信息。

Question

在过去的2天里，我一直在尝试让我的Django Channels应用在Heroku上运行，但似乎无法让它工作。最近，我甚至无法运行该应用程序，但经过一些调查，我设法启动它。该应用程序在本地主机上运行良好。我从有错误404，到500，现在504。我一直在尝试了解Heroku日志，但似乎找不到解决方案。希望有人能给我一个提示，如何解决它.这里是不同的文件和日志。

设置。

CHANNEL_LAYERS = {
    'default': {
        'BACKEND': 'channels_redis.core.RedisChannelLayer',
        'CONFIG': {
            "hosts": [os.environ.get('REDIS_URL', 'redis://localhost:6379')],
        },
    },
}

要求：

Django==3.0.7
gunicorn==19.9.0
pytz==2019.3
sqlparse==0.3.0
whitenoise==5.0.1
tweepy==3.8.0

发现我的错误，是最愚蠢的错误。错误是在我的路由，输入 "wsspanelorder "以为wss部分是我的协议。
