Unable to call a Spring boot Rest Endpoint from arangodb Foxx service in a docker network

Question

I have two services deployed as a docker container on Linux.

• app on arangodb Foxx (arangodb version 3.5.7)
• Spring boot app that has some rest endpoints

CONTAINER ID   IMAGE                COMMAND                  CREATED         STATUS        PORTS                                       NAMES
463bd83993fc   rtm-service:latest   "java -jar rtmapp.jar"   15 hours ago    Up 15 hours   0.0.0.0:8085->9096/tcp, :::8085->9096/tcp   rtm-service-container
54ff37336885   arangodb:3.5.7       "/entrypoint.sh aran…"   18 months ago   Up 15 hours   0.0.0.0:8529->8529/tcp, :::8529->8529/tcp   arangodb_1

To make two services talk to each other i have created shared docker network and added both services in it

sdk@W10NCT40:~$ docker network inspect rtm-network

docker network is correct because i am able to call arangodb Foxx service from spring boot app but not the other way around

• Calling rest end point from sprint boot app (rtm-service-container) to arangodb Foxx (arangodb_1) "WORKS FINE".
• Calling rest end point from arangodb Foxx (arangodb_1) to sprint boot app (rtm-service-container) does "NOT WORKS".

As per provided documentation I am using "@arangodb/request" module. So i tried calling spring boot app rest end point from my arangdb foxx service via following code

const request = require("@arangodb/request");
const response = request.get(
        "http://rtm-service-container:8085/rtm/request-management/products-list"
      );
console.log(response)

The following code runs fine but instead of receivng a product-list in i get following error message on arangodb side

[IncomingResponse 500 Could not connect to 'http+tcp://rtm-service-container:8085' 'connect() failed with #111 - Connection refused' empty]

On my spring boot app, I receive no get request.

I am expecting a proper rest call from arangodb foxx service to my spring boot app and should be able to receive products-list as a response.

I am not sure what is wrong here and what should i do to successfully call spring boot rest end point from my arandb foxx service ?,
