I'm running my eureka-server on my localhost. I'm able to register all my other on localhost running services and everthing works like expected.

Now I want to register a service which is running on a linux machine. My properties looks like that:

spring.application.name=myService-service
spring.cloud.config.uri=http://myMachine.domain.lan:8888
server.port=8002
eureka.client.service-url.default-zone=http://myMachine.domain.lan:8761/eureka/

But the service is not able to register on eureka server on localhost. (At the end its the same service which runs on localhost)

I get those exceptions:

java.net.ConnectException: Connection refused
com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

But I'm able to get my configuration files from my config-service running on localhost.

Which configurations do I need to register my service to eureka from linux machine(client) to localhost(server)?

This annotations do I use:

Service:

@SpringBootApplication
@EnableDiscoveryClient
@EnableEurekaClient
public class MyServiceApplication {

Eureka-Server:

@SpringBootApplication
@EnableEurekaServer
public class EurekaServiceApplication {

P.S.:Also the opposit way is not working. Means having eureka server on linux machine and the services on localhost. Get the same exceptions.

Edit1:

Eureka-Server properties:

spring.application.name=eureka-service
spring.cloud.config.uri=http://myMachine.domain.lan:8888
server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
eureka.instance.hostname=KBHWS242.myDomain.lan
eureka.instance.prefer-ip-address=true

Edit2:

testsrv is the linux machine. (172.25.82.108)
