 Azure Event Grid requires a valid HTTPS endpoint for custom webhooks; self-signed certificates aren't accepted. In order to enable traffic from the public internet to your app's Dapr sidecar you need an ingress controller enabled with Dapr. There's a good article on this topic: [Kubernetes NGINX ingress controller with Dapr](https://carlos.mendible.com/2020/04/05/kubernetes-nginx-ingress-controller-with-dapr/).
