Error registering service to eureka server

Question

I am trying to register a client to spring-eureka-server, client deregisters just after registering

eureka-server logs:

Please let me know what could be possibly wrong.

Your client application is starting, registering with eureka server, and then something shuts it down. So before shutting down, the instance de-registers from server. — narendra-choudhary, May 17 '18 at 22:36

Add

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

into Eureka and client app

It really works !!!

@DieterMeemken probably this answer can clear your question: https://stackoverflow.com/a/22409655/3802053 – Vusala Hasanli May 05 '20 at 02:15
seriously, i almost wasted 2 1/2 hours with this error, and finally add this dependency and removed it, then all works fine – Sahan Jan 20 '22 at 12:45

Eureka client deregisters when an app has been shutdown.

Check if there is any other reason why the app is stopping leading to eureka-client deregistering.

For my case, the application was shutting down due to spring-boot-starter-web dependency. After resolving this, the application started well.

Looks like a dependency issue.

If the app works fine (the core functionality) without eureka integration, then try changing the eureka-client dependency version.

I would suggest you to check the following:

Check all the port numbers that you are running
Check for any version issues
Add above web dependency in your eureka pom.xml (it worked for me in Maven projects)
