So, I created a single-node cluster and used Helm to deploy Grafana, Loki, and Promtail. All my containers are running. When I do port forwarding using the following command:
kubectl port-forward pod/loki-grafana-58f7f5d765-26rgk 3000:3000
It shows:
Forwarding from 127.0.0.1:3000 → 3000
But when I open port 3000 in my browser, I get a 502 Bad Gateway - nginx error.
How can I access the Grafana dashboard now?
