Hi, I am new to Elasticsearch. What I managed to do so far is to bring up ElasticSearch container and successfully connect to it using both http connection(via Postman) and using python client.
However, now I want to bring up such a container not on my machine. And I managed to bring this machine up and connect using http call. But when I try to connect through python client I get this error:
```auto
elastic_transport.TlsError: TLS error caused by: TlsError(TLS error caused by: SSLError(hostname '34.116. ***.***' doesn't match either of 'localhost', '172.19.0.2', '127.0.0.1', 'bde723133f75'))
```
How I connect:
```auto
es = Elasticsearch(
https://34.116. ***.*** :9200",
ca_certs=cert.crt,
basic_auth=(elastic_user, elastic_password),
)
```
Error occurres on this line `res = es.search(index="pdf-documents", query=query)`

Welcome to our community! 😃
What are your Elasticsearch and docker config?

I am using docker-compose:
```auto
elastic:
container_name: elastic
image:
docker.elastic.co/elasticsearch/elasticsearch:8.3.2
ports:
- "9200:9200"
- "9300:9300"
```
And I did not configure anything more in Elastichsearch just copied cert and resetted password
