[Channels] Maybe about daphne?Or not ,I'm not sure.

[CrazyNPC]

I run daphne in docker container on AWS ECS behind AWS ALB.

I found that, when I  configure secure group of the EC2 instance in the ECS cluster to Allow Anyway,  the site is ok, but configure to only Allow the secure group of ALB,

then the flow can't reach.

Curiously, when I use the same config and code , but with gunicore is ok.

So, my question is there some special setting in daphne about this?
