I'm following the tutorial to run a containerized application on Azure AKS on https://docs.microsoft.com/en-us/azure/aks/tutorial-kubernetes-deploy-application but my deployment failes to create a load balancer for my service:

When running kubectl get service myservice --watch the external ip just stays in status pending. What could be the cause of this?
