Docker - Communication between two PHP containers: "Connection Refused" - php

Question

So, I have a problem with my docker setup for a project I'm working on. Using Docker and docker-compose I have set up a few containers as seen below. I can reach both php services via the browser no problem. dev.drmobile.local refers to the Magento service and dev.dronline.local refers to the Symfony service. The problem is that when the Magento service needs data from the Symfony service, I get an error stating Unable to Connect to tcp://dev.dronline.local:80. Error #111: Connection refused. I have tried merging both services in 1 container, but the problem is also present in that situation.
All other communication between containers seems to work fine.
I'm not sure on the port setup I've used, but it doesn't seem to trigger any errors.
Both php containers use the same image created from a Dockerfile, with a slightly different init script.
Any help and tips will be greatly appreciated.
