Unable to connect grafana with loki - helm

[henres]

Describe the bug
Hello everyone,

I am trying to install loki on a kubernetes cluster, I followed this set up : https://grafana.com/docs/loki/latest/setup/install/helm/install-microservices/#install-the-microservice-helm-chart.

Everything seem to work fine on loki side.
I have also installed in another namespace prometheus-stack chart.
I am trying to connect grafana and loki together, but I just got the : Unable to connect with Loki. Please check the server logs for more details. And when I go see the logs of the grafana pods or loki pods. There is no logs.

I have all this services in loki:

loki-backend                              ClusterIP   10.3.39.241    <none>        3100/TCP,9095/TCP    16h

I tried with all 3100 port or the gateway but nothing seem to work ...
If anyone can help me ? Thanks in advance !
Have a nice day (edited)

To Reproduce
Steps to reproduce the behavior:
I followed the https://grafana.com/docs/loki/latest/setup/install/helm/install-microservices/#install-the-microservice-helm-chart
I add the s3 storage (OVH) and change everything to 1 replica.

Be able to connect to grafana via either service and get log error that is verbose if connection error.

Environment:

• Infrastructure: Kubernetes
• Deployment tool: helm

I tried to add datasources directly in the prometheus-stack for grafana :

grafana:
  additionalDataSources:
  - access: proxy
    isDefault: true
    name: loki
    type: loki
    url: http://loki-fa9eeafd-gateway.loki.svc.cluster.local

The grafana pods doesn't start anymore with no logs at all. Neither in loki or grafana.
