Private AKS cluster, enabled outbound, metrics pod keeps failing

Hello,
I have private AKS cluster with open outbound connection and UAMI. I have tried to enable managed prometheus for metrics collections but it seems to fail. Can someone help? I followed this guide https://learn.microsoft.com/en-us/azure/azure-monitor/containers/kubernetes-monitoring-enable?tabs=cli

I tried to look at https://learn.microsoft.com/en-us/azure/azure-monitor/containers/prometheus-metrics-troubleshoot to find solutions here but it did not help. for example

• Checked if UAMI has metric publish role
• DCE and DCR are created, not sure how they work though

Start with the AKS managed Prometheus enablement and troubleshooting guides linked in the report, then inspect the ama-metrics pod logs and the UAMI, DCE, and DCR configuration. Done means identifying the configuration or connectivity cause of the failing metrics extension and documenting a reproducible fix or actionable diagnosis.
