Error adding Loki and Prometheus data sources in Grafana after installing via Helm

Monitoring and Observability Grafana
1

Hi folks! i have some issue adding the loki and prometheus datasource to my grafana. i’ve installad using the following steps:

helm install grafana grafana/grafana --version 6.49.0
helm install loki grafana/loki --version 3.8.0 --set read.replicas=1,write.replicas=1
helm install prometheus-stack prometheus-community/kube-prometheus-stack --version 43.2.1 --set grafana.enabled=false```
when i try to add loki datasource [http://loki-read.default.svc.cluster.local:3100](http://loki-read.default.svc.cluster.local:3100) i receive an error. the grafana log say:

Hey , this works for me, maybe give it a shot?

  datasources.yaml:
    apiVersion: 1
    datasources:
    - name: prometheus
      type: prometheus
      access: proxy
      orgId: 1
      uid: prometheus
      url: [http://prometheus-server.monitoring.svc.cluster.local:80](http://prometheus-server.monitoring.svc.cluster.local:80)
      isDefault: true
      jsonData:
        timeInterval: "5s"
      version: 1
      editable: true
      basicAuth: true
      basicAuthUser: <username>      
      basicAuthPassword: <password>
    - name: loki
      type: loki
      access: proxy
      orgId: 1
      url: [http://loki.logging.svc.cluster.local:80](http://loki.logging.svc.cluster.local:80)
      isDefault: false
      jsonData:
        maxLines: 1000
      version: 1
      editable: true
      basicAuth: true
      basicAuthUser: <username>      
      basicAuthPassword: <password>```
