elastic_transport.TlsError: TLS error caused by: TlsError

[leizhu1989]

hello, author

my environment：
system：windows11
python：3.7
elasticsearch：8.1.2
elasticsearch-py：8.1.2
elastic-transport：8.1.2

when I run demo:

from elasticsearch import Elasticsearch

es = Elasticsearch(
    "https://localhost:9200"
)
resp = es.info()
print (resp)

I got this error

Traceback (most recent call last):

    resp = es.info()

    raise err from None
elastic_transport.TlsError: TLS error caused by: TlsError(TLS error caused by: SSLError([SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1091)))

@leizhu1989 Starting with Elasticsearch 8 we introduced a security by default approach. That means you need to connect using TLS and providing authorization (i.e. certificate). You can read how to connect to a self managed Elasticsearch in the documentation. Let me know if you need more help, thanks!

I will try again , Thank you for your reply!

For reference, WRONG_VERSION_NUMBER usually means that you're trying to connect to an HTTP endpoint using HTTPS. The fix in your case is to specify http://localhost:9200 instead of https://localhost:9200.
