Unable to connect to Command Metric Stream. in Hystrix Dashboard issue

Before posting this question, I went through numerous links like : Unable to connect to Command Metric Stream for Hystrix Dashboard with Spring Cloud and Unable to connect to Command Metric Stream in Spring Cloud + Hystrix + Turbine - MIME type ("text/plain") that is not "text/event-stream" and so on, but still things are not working for me.

I am using Spring Boot V2.2.2.RELEASE.

in dashboard project add this to your properties

hystrix:
  dashboard:
    proxy-stream-allow-list: "*"

and, in weather-app add this

management:
  endpoints:
    web:
      exposure:
        include: "*"

then, open http://localhost:8080/hystrix and add http://localhost:8000/actuator/hystrix.stream
