Hi all,

I'm trying to setup log stash for my elasticsearch master region to backup region for our BCP, I will be using the in and out information of logstash however, I got an error

```auto
[2023-02-22T07:14:21,226][ERROR][logstash.outputs.elasticsearch][main] Attempted to send a bulk request to elasticsearch, but no there are no living connections in the connection pool. Perhaps Elasticsearch is unreachable or down? {:error_message=>"No Available connections", :class=>"LogStash::Outputs::ElasticSearch::HttpClient::Pool::NoConnectionAvailableError", :will_retry_in_seconds=>4}
[2023-02-22T07:14:23,140][WARN][logstash.outputs.elasticsearch][main] Restored connection to ES instance {:url=>"http://backupRegionIP:9200/"}

```

I did try curl -v backupRegion:9200 from the master region and I was able to connect.

I really appreciate any help you can provide.

Thanks,

---
