kubernetes ingress external-dns aws-route53 yaml

Can someone help me understand I'm integrating two systems and I'm having a hard time understanding I'm working on a personal project and I'm facing an issue where my Kubernetes Ingress resource is not resolving the specified hostname to the right service. I'm using NGINX Ingress Controller with ExternalDNS to manage DNS records in AWS Route 53. After deploying, the Ingress resource is created successfully, but when I try to access it via http://myapp.example.com, I get a 404 error instead of the expected response. Here are the relevant configurations I have: My Ingress resource looks like this: ```yaml apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: myapp-ingress annotations: kubernetes.io/ingress.class: nginx spec: rules: - host: myapp.example.com http: paths: - path: / pathType: Prefix backend: service: name: myapp-service port: number: 80 ``` The associated service definition is: ```yaml apiVersion: v1 kind: Service metadata: name: myapp-service spec: selector: app: myapp ports: - port: 80 targetPort: 8080 ``` I also have the ExternalDNS deployment configured like this: ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: external-dns spec: replicas: 1 selector: matchLabels: app: external-dns template: metadata: labels: app: external-dns spec: containers: - name: external-dns image: k8s.gcr.io/external-dns/external-dns:v0.10.2 args: - --source=service - --domain-filter=example.com - --provider=aws - --policy=upsert-only - --registry=txt ``` I confirmed that the DNS records are created in Route 53, but the hostname isn’t resolving to the correct IP of the Ingress controller. I’ve checked that the Ingress controller is up and running, and I can see the traffic being processed in its logs, but it consistently returns a 404 for requests to the hostname. I’ve tried restarting both the Ingress Controller and the ExternalDNS pod, but the issue persists. Any insights on what might be causing this misconfiguration? Is there a specific sequence or dependency I might be missing? For context: I'm using Yaml on macOS. Any help would be greatly appreciated! I'm using Yaml 3.11 in this project. Thanks for taking the time to read this! For context: I'm using Yaml on Debian. This is my first time working with Yaml latest. Any advice would be much appreciated.
