I installed Grafana on a Raspberry Pi and have problems to get Loki running.
My Grafana is on v9.4.3, and I installed it by following this tutorial: Install Grafana on Raspberry Pi | Grafana Labs
But if I create Data source Loki it does show me a red label Unable to fetch labels from Loki (Failed to call resource), please check the server logs for more details
My Grafana Logs show this:
$sudo tail -n 5 /var/log/grafana/grafana.log

How can I verify if Loki is installed correctly?
Am I overlooking something I had to do previously?
