Need help - xdcr replication to ES stopped

Right now same issue is happening with me where I am trying to create replication between elastic search VM and couch base . It is throwing error :- cannot find remote cluster err = Failed to connect to cluster reference remoteCluster/tSuocSQaJUkgl-BdFw–3a0DfS7PZtm9iED0YlYIjv0.

I am using following guide :- https://developer.couchbase.com/documentation/server/4.6/connectors/elasticsearch-2.2/getting-started.html

And I am on create replication step.

There is an issue logged for it https://github.com/couchbaselabs/elasticsearch-transport-couchbase/issues/144

Does anybody have an Idea what it is ? and if it is something when it can be resolved?

Is there any work around for it? Does elastic search works only when it got a local node with it?
