Bugs make connection to Grafana Cloud impossible:

  • Wrong Token value = from url configuration
  • Miss HTTPS feature for opentelemetry-otlp reqwest-rustls

After that, the connection is working. I've completed the documentation to indicate how to configure Grafana Cloud OpenTelemetry with direct connection for ProSA.

Also there is a bug with new release of Prometheus because the header Content-Type is missing.
It should be set as defined in the Grafana documentation for text protocol.
