ok , do you have any sample application atleast with git-hub that i could refer?? Would appreciate it if you would

Well, spring boot admin fetches data from service discovery, right? So, you should see

thanks , do you have any sample application over https??

Yes, I’m able. First you need to generate self-signed certificate, for example using keytool.
And then enable https for Spring Boot app and for Eureka client.

server:
port: ${PORT:8081}
ssl:
key-store: classpath:keystore.p12
key-store-password: 123456
keyStoreType: PKCS12
keyAlias: client

eureka:
client:
serviceUrl:
defaultZone: ${EUREKA_URL:http://localhost:8761/eureka/}
instance:
securePortEnabled: true
nonSecurePortEnabled: false
statusPageUrl: https://${eureka.hostname}:${server.port}/info
healthCheckUrl: https://${eureka.hostname}:${server.port}/health
homePageUrl: https://${eureka.hostname}:${server.port}/

You can take a look on that example https://github.com/piomin/sample-spring-cloud-netflix.git, branch secure_client.
