Why does elastic raise this exception "elasticsearch.exceptions.ConnectionError: ConnectionError(check_hostname requires server_hostname)"?
Unfortunately, I also met such issue.
By default, the value of check_hostname in context is True, so you have to specify the server_hostname. Here is a simple solution, just add the following line after you create context
context.check_hostname = FalseIt should work without any issue
You don't mention the port in your example. Please verify the tutorial you mentioned and following snippet:
es = Elasticsearch( ['localhost', 'otherhost'], http_auth=('user', 'secret'), scheme="https", port=443,)
By doing context.check_hostname = False you make the connection insecure.
Use this constructor instead:
Elasticsearch( hosts=['ip_address'],, http_auth=('elastic', 'pass'), use_ssl=True, verify_certs=True, port=9200, #make sure of the port elasticsearch is using ca_certs='/Users/raphaeldelio/ca.crt')
