#disable certificate
es = Elasticsearch(hosts="https://localhost:9200", basic_auth=(USER, PASS), verify_certs=False)

#if getting an issue relevant to the certificate then:
es = Elasticsearch(hosts="https://localhost:9200", basic_auth=(USER, PASS), ca_certs=CERTIFICATE, verify_certs=False)

# I hope you know where to find certificate, e.g:
$ find /usr/share/elasticsearch -name "certs.pem"
