I already went through many links like @RefreshScope and /refresh not working and Spring Boot 2: Refresh properties on the fly not working, but still things are not working for me.
I've developed spring-cloud-config-server
when I hit
POST ==> http://localhost:8002/actuator/refresh
I get the response
[ "config.client.version" ]
It looks like its somehow not loading the changed properties
