nginx ingress not working in aks always 404 - docker

Question

I have a setup of aks with
movie-service deployed
nginx ingress deployed
NAME READY STATUS RESTARTS AGE
movie-service-7bbf464749-ffxh6 1/1 Running 0 45m

Normal AddedOrUpdated 44m (x3 over 44m) nginx-ingress-controller Configuration for default/movie-service was added or updated
But when I check my path configuration inside nginx container I can't see anything
kubectl exec -it nginx-release-nginx-ingress-7c97fd9dd7-qdcjw sh
kubectl exec [POD] [COMMAND] is DEPRECATED and will be removed in a future version. Use kubectl exec [POD] -- [COMMAND] instead.
$ ls -lrt /etc/nginx/conf.d
total 0 ```
Observations :
1. My movie-service api is working fine - when i go inside container and hit with localhost.
2. /nginx-health url works fine and gives 200 OK response.

Same issue out here.

https://docs.nginx.com/nginx-ingress-controller/installation/installation-with-manifests/
path: /applike
path based routing isint working at all......
path: / - just the default path works and provides a response from the specified service.
