Hello,
after installing the Grafana K8s monitoring stack using a Grafana cloud instance and following the guided installation through Grafana, I am experiencing issues with exporting the metrics to the cloud instance.
I am getting the following error message in my alloy-receiver:
ts=2025-05-31T18:22:18.379381935Z level=error msg="Exporting failed. Dropping data." component_path=/ component_id=otelcol.exporter.otlphttp.grafana_cloud_otlp_endpoint error="not retryable error: Permanent error: rpc error: code = Unauthenti ││ cated desc = error exporting items, request to https://otlp-gateway-prod-eu-west-2.grafana.net./otlp/v1/metrics responded with HTTP Status Code 401" dropped_items=7
I double and tripple checked the credentials provided to the receiver and they are identical to the ones used for the other Grafana Pods. For example singleton-remote.
I also checked the permissions on the cloud access policies and I believe they are correct.
Sincerely
Jan
