Django + React + Regis - Find BUG in my code to run in DOCKER -- 3

Hi, I'm trying to run my React + Django + Regis with docker and I'm having an error. It works outside of docker but when in docker it doesn't work Note: I'm using django channels to use chat functionality which requires regis to run What does work? - Able to connect to http://localhost to access frontend - Able to connect to http://localhost:8000 to access backend What doesn't work? - WebSocket connection to 'ws://[login to view URL]' failed: I think this has to do with regis not running/setup properly inside the docker containers, because when running it outside of docker it works perfectly by starting regis this way docker run -p 6379:6379 -d redis:5 [login to view URL] Django [login to view URL] CHANNEL_LAYERS = { 'default': { 'BACKEND': '[login to view URL]', 'CONFIG': { "hosts": [('redis', 6379)], }, }, }
