Source-controller Leader Election Errors - Timeout/Connection Issues (v1.5.0)

Il report fornisce i log di source-controller v1.5.0 provenienti da un cluster AKS 1.29.4v, ma non indica alcun file sorgente, test o punto di ingresso. Iniziare correlando gli errori di leader-election con la connettività tra il pod e l’API-server e con le metriche pertinenti del controller o di AKS; il lavoro sarebbe concluso una volta identificata una causa riproducibile e una raccomandazione documentata di configurazione o diagnostica.

We're encountering issues with the source-controller in our Azure Kubernetes Service (AKS - 1.29.4v) cluster, and I'm hoping someone can offer some guidance. We are running source-controller version 1.5.0.

We're seeing the following errors repeatedly in the source-controller pod logs:

{"level":"error","ts":"2025-05-24T08:51:05.665Z","logger":"runtime","msg":"Failed to update lock optimistically: Put \"https://10.0.0.1:443/apis/coordination.k8s.io/v1/namespaces/flux-system/leases/source-controller-leader-election?timeout=15s\": net/http: request canceled (Client.Timeout exceeded while awaiting headers), falling back to slow path"}
{"level":"error","ts":"2025-05-24T08:51:20.652Z","logger":"runtime","msg":"error retrieving resource lock flux-system/source-controller-leader-election: Get \"https://10.0.0.1:443/apis/coordination.k8s.io/v1/namespaces/flux-system/leases/source-controller-leader-election?timeout=15s\": context deadline exceeded"}
{"level":"error","ts":"2025-05-24T08:51:30.653Z","logger":"runtime","msg":"Failed to release lock: Put \"https://10.0.0.1:443/apis/coordination.k8s.io/v1/namespaces/flux-system/leases/source-controller-leader-election?timeout=15s\": http2: client connection lost"}
{"level":"error","ts":"2025-05-24T08:51:30.659Z","logger":"setup","msg":"problem running manager","error":"leader election lost"}

Are there any known issues or configuration recommendations specific to AKS that might be relevant?
What are the recommended ways to diagnose network connectivity issues between pods and the API server within AKS?
Are there any specific metrics we should be monitoring to help identify the root cause of these errors?

Thanks in advance for any help you can provide!
