Hyy👋,

```
     My Elasticsearch is running properly but sometimes it shows this error .

```

- Attempted to send a bulk request but there are no living connections in the pool (perhaps Elasticsearch is unreachable or down?) {:message=\>"No Available connections", :exception=\>LogStash::Outputs::Elasticsearch::HttpClient::Pool::NoConnectionAvailableError, :will\_retry\_in\_seconds=\>4}

.In elasticsearch some datas are not available i think because of this problem.when i'm checking the cluster health its been yellow and unassigned shards are 2.
