Not able to get the Metric charts displayed using Hystrix dashboard in Bluemix

I am trying to use Hystrix to implement service proxy to implement circuit breaker pattern. I did implement the Hystrix Commands and also package the Hystrix servlet to provide the Hystrix stream. To monitor the services, I am using the Hystrix Dashboard 1.5.0. All works fine on a local Tomcat server. I am able to see the metrics charts

However, when I deploy the same on Bluemix, the Dashboard does not show the charts. Instead it says 'Unable to connect to Command Metric Stream.'. I also checked the stream using Chrome browser. I am able to see the messages as below:

Any idea, why the Dashboard is not able to connect to stream when deployed on Bluemix. Any help is appreciated.

I have the same exact problem trying to run on Bluemix. I also run fine locally using Spring Tools Suite. Has there been a resolution to this problem?

My situation: I used the Spring Initialzr to create a Spring Cloud application (Eureka, Hystrix, REST controller). I have deployed this to Bluemix (Cloud Foundry). Everything works fine except the Hystrix dashboard. I get "Unable to connect to Command Metric Stream." on the dashboard.

I can curl the stream url - it takes a really long time but data does come back.
