Alloy: authentication error: invalid token

Grafana Installation
1

Hello, I’m using Grafana Cloud and on my node that I want to monitor logs from, when running ./alloy-linux-amd64 run config.alloy I am getting error:

level=error msg="final error sending batch"
component_path=/remotecfg/self_monitoring_logs_linux.default
component_id=loki.write.grafana_cloud_loki component=client
host=logs-prod-024.grafana.net status=401 tenant=""
error="server returned HTTP status 401 Unauthorized (401):
{\"status\":\"error\",\"error\":\"authentication error: invalid token\"}"

What surprises me is that all configurations have been made using the Grafana Cloud provided script for both Alloy and Collector.

I cannot test the credentials because Grafana Cloud disables access to them:

My config.alloy as follows:

cat config.alloy
