Spring Cloud Config + Eureka + Zuul - not seeing properties in clients - spring-cloud

Question

I am developing an application with microservice-based arhitecture using Spring Cloud.
I have four applications currently in project:
config-server, eureka-server, gateway-service(zuul) and eureka-client which I am using just to test that the project works as intended.
But I have a problem fetching properties from the config-server.
I have a git repository in which I have one file, eureka-client.yml.
This file has one property message: test message.
I can see that the property is loaded into the config-server if I go to http://localhost:8888/eureka-client/default.
But when I access the property in my eureka-client it returns null.
environment.getProperty("message");
Could someone tell me what am I doing wrong? I'm probably just missing a configuration or .yml property but can't find out which one.
Also the clients are supposed to fetch the properties from the config-server through Eureka.
EDIT:
eureka-server - application.yml
server:
port: 8761
eureka:

hostname: localhost
client:

eureka-client - application.yml
