I encountered the same problem as you. Finally I found the missing rbac. I solved it by the following method:

  1. get sa loki-promtail

kubectl get sa -n loki

NAME                SECRETS   AGE
default             1         17h
loki                1         41m
loki-grafana        1         41m
loki-grafana-test   1         41m
loki-promtail       1         41m
  1. create ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: promtail-clusterrole
rules:
  - apiGroups: [""]
    resources:
    - nodes
    - services
    - pods
    verbs:
    - get
    - watch
    - list
  1. create ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: promtail-clusterrolebinding
subjects:
    - kind: ServiceAccount
      name: loki-promtail  # your promtail sa
      namespace: loki
roleRef:
  kind: ClusterRole
  name: promtail-clusterrole
  apiGroup: rbac.authorization.k8s.io
