过去2天，我一直在尝试让我的Django Channels应用程序在Heroku上运行，但似乎无法使其正常运行。我最近什至无法运行该应用程序，但经过一番挖掘后，我设法将其启动。该应用程序可以在localhost上正常运行。我从出现错误404到500，再到504。我一直在尝试了解Heroku日志，但似乎找不到解决方案。希望有人可以给我提示如何解决它。 这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
dj-database-url==0.5.0
psycopg2-binary==2.8.5
discord.py==1.3.3
requests==2.23.0
channels-redis==2.4.2
channels==2.4.0
daphne==2.5.0

asgi.py

import os
import django
from channels.routing import get_default_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE','APPNAME.settings')
django.setup()
application = get_default_application()

Procfile：

web: daphne APPNAME.asgi:application --port $PORT --bind 0.0.0.0 -v2
