Unable to detect the Elasticsearch version running on the cluster:

Hibernate Search

We are getting this error after migration in HS 6. We are getting this error for only default spring profile.
(It was working fine for default profile in HS 5) . Any reason??

Hibernate Search encountered failures during bootstrap. Failures: default backend: failures: - HSEARCH400080: Unable to detect the Elasticsearch version running on the cluster: HSEARCH400007: Elasticsearch request failed: Connection refused Request: GET with parameters {}\nResponse: (no response)

We wondered we have not configured elastic search endpoint anywhere in the application and still able to connect with elastic search server to fetch data in HS 5.
