http addon using Ingress, NGINX Ingress Controller and ExternalName Service

[shreya0910]

I am trying to setup keda + httpadd on is in keda namespace & application + ingress is in app ns. Created Ingress, NGINX Ingress Controller and ExternalName Service setup(in app ns)

Here is the external service manifest
apiVersion: v1
kind: Service
metadata:
name: demo-externalname
namespace: app
spec:
type: ExternalName
externalName: keda-add-ons-http-interceptor-proxy.keda.svc.cluster.local

but so far its not working as expected
keda-add-ons-http-interceptor-proxy is not reachable from nginx. Here is the log

[26/Apr/2024:22:31:42 +0000] "GET /path HTTP/1.1" 499 0 "-" "-" 120 15.993 [apps-keda-add-ons-http-interceptor-proxy-8080] []
[26/Apr/2024:22:31:42 +0000] "GET /path HTTP/1.1" 502 150 "-" "-" 120 2.025 [apps-keda-add-ons-http-interceptor-proxy-8080] []

Has anyone setup in similar way and achieved success
