Timeout Exception When Calling Downstream Services (HttpClient.Timeout). [Assistance with Better Logging]

[chawlaheena21]

Our Service is leveraging the SDK to make http calls to downstream service. For some intermittent calls, we are observing the following error -

Incoming exception: The request was canceled due to the configured HttpClient.Timeout of 100 seconds elapsing.

The requests didn't reach the downstream service and there was another log - An error occurred while sending the request.

Can you help us understand the underlying cause of this timeout exception?
Is there any specific configuration or condition that could cause the request to be canceled before it reaches the downstream service?

Is it possible to enable more detailed logging (e.g., debug or trace level) in the SDK to help us understand what's happening in the client-side communication and where the timeout is occurring?

The c# SDK also makes use of OpenTelemetry if you are able to plug into that.
