Marbles image in docker network unable to resolve CA hostname

[httran13]

I am running a marbles docker image in the same network with my fab network.
Using the docker container's name as the hostname, marbles is unable to connect to the fabric ca(http protocol) but marbles is able to resolve the peers/orderers.

How I had to temporarily get marbles working, hence i know that its able to connect to peers/orderers using the dockers given hostnames, is using the marbles ui guided help, I input the fabric ca IP.

I got the fabric ca IP by using docker network inspect, only when using the IP, marbles were able to function correctly.

are you using the "my first network" setup from fabric-samples? this seems more of a problem with your network's setup than with marbles. I'm stating the obvious here, but you need to specify the hostname to docker: docker run --hostname=value

im using docker-compose file and both marbles and ca is in the same network "projbc".

Below is my local connection_profile
