Hi Valerio Maglietta,

Welcome to Microsoft Q&A Platform. Thank you for posting your query here!

I suggest you check for expiration of certificates by running below command:
az connectedk8s show -n <cluster-name> -g <resource-group> --query "managedIdentityCertificateExpirationTime"
https://learn.microsoft.com/en-us/azure/azure-arc/kubernetes/workload-identity

Check for Network/firewall restrictions blocking outbound HTTPS traffic to this domain.
Checking the logs of the Azure Arc agent extension-agent pod logs. You can find the pod by running: kubectl logs -n kube-system extension-agent-<pod-guid>
