How to connect to 0.0.0.0 from inside a docker container?

Question

Docker

I have two docker-compose.yml config files.
In one file, I launch a service that is displayed at 0.0.0.0:15672 (everything works fine in the browser)
And in the second file, I raise a service that interacts with the service from the first file.

But when I try to connect to 0.0.0.0:15672 from the second service, it gives a Connection Error.
If you start the second service without docker - everything works.
If you wrap it in a docker - no.

How to fix it?

PS - The option to combine two config files into one and connect by container name is not suitable.

By default, each file has its own subnet.
In order for both applications to work on the same network, then as an option, create a network in one docker-compose.yml and use the same network with the external: true flag in the second.
