Error while executing a query using elastic search python API

Question

I am not able to execute a query on elastic db using elasticsearch python api. I see the following error. I am getting Ping as True to the elastic object. Can anyone help me with this issue?

es = Elasticsearch(
    ['localhost', 'otherhost'],
    http_auth=(username,pwd),
    port=port_no,
    use_ssl=False
)
>>> es.ping
    True


>>> es.count(index="events-2017.06.09*")
Traceback (most recent call last):

Did you already try to connect with a web browser or with curl ? Which client tools did you use to connect to ES ?

For example this a client runnung as plugin google chrome: Elastic Search Query Builder

NotFoundError represents 404 , which means ES did not find the resource you requested.

You didn't indicate a port number, so it defaults to port 80. Very often on this port there is a web server installed. And probably your ES runs on a different port eg 9200. And this could explain why you receive a 404 as the web server on 80 does not know about your index.
