I'm using Django Channels in my app to make a person to person chat function. For this I'm using *Django Channels channel layers* that uses 'Redis' as a backing store.
I have following configuration in the settings.py: CHANNEL_LAYERS = { "default": { "BACKEND": "channels_redis.core.RedisChannelLayer", "CONFIG": { "hosts": [os.environ.get('REDIS_URL', ("localhost", 6379))], }, }, } The CHANNEL_LAYERS is working fine for development when 'hosts' points to localhost. However for production, when I'm trying to make sure that the channel layer can communicate with Redis on Heroku it does not work. Using code as giving in Channels Docs <https://channels.readthedocs.io/en/stable/tutorial/part_2.html> as shown below, gives the following error import channels.layers >>> channel_layer = channels.layers.get_channel_layer() >>> from asgiref.sync import async_to_sync >>> async_to_sync(channel_layer.send)('test_channel', {'type': 'hello'}) Traceback (most recent call last): File "<console>", line 1, in <module> File "/app/.heroku/python/lib/python3.7/site-packages/asgiref/sync.py", line 223, in __call__ return call_result.result() File "/app/.heroku/python/lib/python3.7/concurrent/futures/_base.py", line 428, in result return self.__get_result() File "/app/.heroku/python/lib/python3.7/concurrent/futures/_base.py", line 384, in __get_result raise self._exception File "/app/.heroku/python/lib/python3.7/site-packages/asgiref/sync.py", line 292, in main_wrap result = await self.awaitable(*args, **kwargs) File "/app/.heroku/python/lib/python3.7/site-packages/channels_redis/core.py", line 299, in send async with self.connection(index) as connection: File "/app/.heroku/python/lib/python3.7/site-packages/channels_redis/core.py", line 835, in __aenter__ self.conn = await self.pool.pop() File "/app/.heroku/python/lib/python3.7/site-packages/channels_redis/core.py", line 73, in pop conns.append(await aioredis.create_redis(**self.host, loop=loop)) File "/app/.heroku/python/lib/python3.7/site-packages/aioredis/commands/__init__.py", line 175, in create_redis loop=loop) File "/app/.heroku/python/lib/python3.7/site-packages/aioredis/connection.py", line 133, in create_connection await conn.auth(password) File "/app/.heroku/python/lib/python3.7/site-packages/aioredis/util.py", line 52, in wait_ok res = await fut File "/app/.heroku/python/lib/python3.7/site-packages/aioredis/connection.py", line 186, in _read_data obj = await self._reader.readobj() File "/app/.heroku/python/lib/python3.7/site-packages/aioredis/stream.py", line 102, in readobj await self._wait_for_data('readobj') File "/app/.heroku/python/lib/python3.7/asyncio/streams.py", line 473, in _wait_for_data await self._waiter File "/app/.heroku/python/lib/python3.7/asyncio/selector_events.py", line 814, in _read_ready__data_received data = self._sock.recv(self.max_size) ConnectionResetError: [Errno 104] Connection reset by peer Request for urgent help please!! -- You received this message because you are subscribed to the Google Groups "Django users" group.
