I followed like a code like this:

```auto
import elasticsearch
from langchain_elasticsearch import ElasticsearchStore
es_client= elasticsearch.Elasticsearch(
    hosts=["https://ip:host"],
    es_user="elastic",
    es_password="changeme"
    max_retries=10,
)

embedding = OpenAIEmbeddings()
elastic_vector_search = ElasticsearchStore(
    index_name="test_index",
    es_connection=es_client,
    embedding=embedding,
)

```

However, this error occurred.

elastic\_transport.TlsError: TLS error caused by: TlsError(TLS error caused by: SSLError([SSL: WRONG\_VERSION\_NUMBER] wrong version number (\_ssl.c:1133)))

How can I connect Elasticsearch to langchain?

I'm followed this url [Elasticsearch | 🦜️🔗 LangChain](https://python.langchain.com/docs/integrations/vectorstores/elasticsearch/)
