These three containers are running and communicating with each other just fine.

Performing inspect shows they are all running through a network called “cedalo-platform” (output shown at end of this message)
> docker network ls
NETWORK ID NAME DRIVER SCOPE
098da67fe363 bridge bridge local
3302dd7e3329 cedalo-platform bridge local
2b748a0a31c8 host host local
069a6a05126f none null local
c163d8ad4267 todo-app bridge local
I then start up a container for a gateway-bridge.The docker-compose yaml specifies that it should be on the cedalo-platform network and that this network is external. Despite whether I use tcp://0.0.0.0:1883 or if I used tcp://127.0.0.1:1883 neither of these will connect. In fact the error that appears (“connection refused”) is identical as if I had not even started the above three containers. It is as if it cannot see this port at all.
Try 0.0.0.0 connection refused.

This is the YAML that I am using showing cedalo-platform and listed external.
version: "3.6"

stdin_open: true # docker run -i

The following is further proof that the three containers are bundled into the network called cedalo-platform I am completely stuck and need any advice to proceed.
