eureka-server:8002 - was unable to send heartbeat

Solution 1
The stacktrace you have shared, can be because a microservice is unable to access your Eureka server. "DiscoveryClient_EUREKA-SERVER/LT-BSSYFY1.XXXXXXX.in:eureka-server:8002 - was unable to send heartbeat!".
Sometimes maybe when we are trying to run the Eureka Server application on our local we need to add entry in hosts file: /etc/hosts file:
127.0.0.1 -ServerName-
Check your Eureka Config. Most production environments have a setup like this:
Eureka Server: How to achieve high availability
Code a couple of basic SpringBoot microservice and add configuration in their bootstrap.yml to connect with your Eureka Server and try invoking SpringBoot app "B" from Spring Boot app "A", using the spring application name and not the IP/Port. This will be done with the help of Eureka/Ribbon. On Eureka both your applications will get registered and then client side load balancing with take place with Ribbon to invoke the other microservice.
Once you get this local setup running and get a hold of things, try to contrast with your production code and see where the issue is.
Solution 2
I faced the similar issue. And in my case, my eureka.client.service-url.defaultZone was configured wrong. Below are my before and after fix eureka server configurations.
Before fix:
spring.application.name=DefectTrackerEureka
server.port=2222
eureka.client.fetch-registry=false
eureka.client.register-with-eureka=false
eureka.client.service-url.defaultZone=http://localhost:2222/defectTrackerEureka
After fix
spring.application.name=DefectTrackerEureka
server.port=2222
eureka.client.fetch-registry=false
eureka.client.register-with-eureka=false
eureka.client.service-url.defaultZone=http://localhost:2222/eureka
I always used to think, that url should be suffixed with the server.application.name. However, apparently, service-url should be suffixed with eureka irrespective of your application name. Now, these configurations, were not giving error while starting eureka server. But, while starting micro-service, i was getting the heartbeat errors. Therefore, i corrected the service-url in all micro-services as well as eureka server and then it worked.

I am new in microservices (with Spring Boot). Copied production code and trying to run on my local. What things should I do for run code successfully? There are config server, eureka server, tomcat server, zuul routing tool, ribbon load balancer, feign client and many more things are used. What necessary steps to run application? Config server is running correctly but eureka server showing issue:
