Grafana cannot connect to loki as a data source however I can shell into the grafana pod and connect to loki.
$ curl http://loki:3100/ready
ready
I see this error message in the grafana logs.

Hi @sawatson,
Could you share which version of Loki and Grafana are you using?
And If applicable, which helm chart?
There’s a recent issue similar in the Grafana repo and it’s related to the Loki-stack helm chart version.
Link here: Grafana Loki Integration: Health check fails when Loki is up and functional · Issue #79846 · grafana/grafana · GitHub
I believe that’s the issue.
NAME CHART APP VERSION
loki loki-stack-2.9.11 v2.6.1
I was able to get it working by removing grafana and enabling Grafana that’s included in the loki-stack.
