ECONNREFUSED when requesting to an endpoint of an Adonis js API

[kempsteven]

I have 2 Dockerized Adonis JS API app running on my local.
I am usingnode-fetch, APP 1 needs to request to APP 2, but I'm receiving ECONNREFUSED error when I do the API call.

When I request the API on the browser or postman it responds properly.

What could be the problem here? Why cant APP1 request to APP2? while browsers and postman can?

So this wasn't exactly an adonisjs problem,

The complete explanation is here https://stackoverflow.com/a/40091406/10020611.

So the problem was that my two docker container is not sharing same network.
First step I did is to identify the network name of my dockerized app using this command
docker network ls

once i got the network name, type this command to see the network details of your app
docker network inspect networkname

That would show you the details of your network:

"IPAM": {
            "Driver": "default",
            "Options": null,
            "Config": [
                {
                    "Subnet": "0.0.0.0/16",
                    "Gateway": "0.0.0.1"
                }
            ]
},

I used the Gateway IP and added the port and was able to access the other dockerized app.
