I have installed and am currently running a working ELK 7.3 on Windows 10 (no docker)
I decided to compare Kibana to Grafana, so I installed Grafana 6.3.2 on the same Windows 10 box (again, no docker)
I set the datasource and index for Grafana to the same ES that is currently feeding Kibana.
So: Add New Datasource -> Elasticsearch
URL is correct (http://localhost:9200
) <- responds to curl
index name is set to the same I used in Kibana
ES Version is 7.0+
Save and Test give me an Error 502
ES version is set to 7.0+
I can curl the URL and get ES stuff back, I can still use Kibana and get at the data. What can I debug to see why Grafana cannot see the ES instance?
