Hi @Bolywar,

I met the same issue in grafana oncall v1.15.0 last week. I think it may be a bug in oncall plugin when RBACEnabled is true.
The error occurred when grafana call API api/plugins/grafana-oncall-app/resources/plugin/status for oncall plugin connection. It will trigger an API call /api/access-control/users/1/permissions to grafana but grafana won't process the path any more.

You could check the log of your grafana pod and find such error log:

logger=context userId=xxx orgId=xxx uname=sa-1-sa-autogen-oncall t=xxx level=info msg="Request Completed" method=GET path=/api/access-control/users/1/permissions status=404 remote_addr=xxx time_ms=5 duration=5.295902ms size=24 referer= handler=notfound status_source=server

You could add a config in grafana.ini to work around the issue.

accessControlOnCall = false

grafana.ini

grafana:
  enabled: true
  grafana.ini:
    server:
      domain: mydomain.net
      root_url: "%(protocol)s://%(domain)s/grafana/"
      serve_from_sub_path: true

      accessControlOnCall: false

solved by replacing the paths

grafana.ini:
    server:
      domain: oncall-grafana.grafana.svc.cluster.local
      root_url: "%(protocol)s://%(domain)s/grafana/"
      serve_from_sub_path: true
    feature_toggles:
      enable: externalServiceAccounts
      accessControlOnCall: false

grafana-oncall-app-provisioning.yaml:
   apps:
      - type: grafana-oncall-app
        name: grafana-oncall-app
        disabled: false
        jsonData:
          stackId: 5
          orgId: 100
          onCallApiUrl: http://oncall-engine.grafana.svc.cluster.local:8080
