We are using java high level rest client to connect to elastic search through spring boot. The spring boot application launches fine from workstation but when we deploy to Pivotal cloud foundry getting the following error intermittently. How to solve this problem?

Elastic search 6.7.2 installed on ubuntu 16.04  
Dependency in POM.xml files

`java.net.ConnectException: Connection refused` seems to say that you can't reach elasticsearch from the machine where your spring application is running.

Did you try to run a simple

```
curl ip:9200 

```

From the same machine?
