Hey @badr !
It looks like the receiver is trying to connect to the wrong queue. From the logs, the Solace Receiver on the OpenTelemetry Collector is trying to connect to the queue #telemetry-tracing whereas in your screenshots the queue name is actually #telemetry-tracing_profile . Can you try changing the queue name in the OpenTelemetry config to match the queue name #telemetry-tracing_profile ?
