Querying Elasticsearch Returns No Data

I’m trying to query ElasticSearch (Version: 5.5.2) from Grafana (Version: 6.3.5) but for some reason the grafana dashboard isn’t fetching any data points from elasticsearch even though there should be data there.

Anyone have any ideas on this?

EDIT:
Looks like I placed the wrong port to another valid ES instance, but not the one I was looking for.
