Failed to update datasource using Grafana

[Giovani_Hoff]

Hi! I am not able to communicate Elasticsearch with Grafana. Please, why is it so hard???

I am running the following versions:
Grafana 6.2.1
Elasticsearch 7.1.0
macOS 10.14.3

From http://localhost:9200 I get
{
"name":"MacBook-Pro-de-Giovani.local",
"cluster_name":"elasticsearch",
"cluster_uuid":"e-Ur6buuRHSLh9V_NuTTBw",
"version":{
"number":"7.1.0",
"build_flavor":"default",
"build_type":"tar",
"build_hash":"606a173",
"build_date":"2019-05-16T00:43:15.323135Z",
"build_snapshot":false,
"lucene_version":"8.0.0",
"minimum_wire_compatibility_version":"6.8.0",
"minimum_index_compatibility_version":"6.0.0-beta1"
},
"tagline":"You Know, for Search"
}

We don't support Grafana on this forum. May be you should ask on Grafana forums?
