Kong-proxy not working inside Jelastic environment

Question

We need a bit of help trying to install Kong in Kubernetes inside Jelastic environment. Me and My colleague have a production based kubernetes cluster with the following:

Load Balancer
- 1 Node with Public IP
Workers
- 2 Nodes
Storage
- 3 Nodes with NFS storage
Control Plane
- 3 Nodes

By default, this environment has ingress-nginx which loads the Hello Kuberenetes application just fine. Here is the config for the ingress-nginx hello kubernetes example:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: helloworld
  namespace: default
spec:
  ingressClassName: nginx
  rules:
  - http:
      paths:
      - backend:
          service:
            name: hello-kubernetes
            port:
              number: 80
        path: /
        pathType: Prefix
status:
  loadBalancer: {}

However, when we install Kong and switch the ingress class to Kong, it returns 404. Some context on how we install Kong:

Setting the config for the metallb-system and assign the public ip address:

apiVersion: v1
data:
  config: |
    address-pools:
    - name: default
      protocol: layer2
      addresses:
      - XXX.XXX.XXX.35-XXX.XXX.XXX.35
kind: ConfigMap
metadata:
  name: config
  namespace: metallb-system

Restarting the controller and the pods in the metallb-system name-space
Installing Kong using the https://raw.githubusercontent.com/Kong/kubernetes-ingress-controller/main/deploy/single/all-in-one-postgres.yaml
It gets assigned the Public IP for the kong-proxy service.
Editing the helloWorld ingress like so and changing the ingressClassName to kong:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: helloworld
  namespace: default
spec:
  ingressClassName: kong
  rules:
  - http:
      paths:
      - backend:
          service:
            name: hello-kubernetes
            port:
              number: 80
        path: /
        pathType: Prefix
status:
  loadBalancer: {}

When the above configs are applied, we get a 404 Not found by Nginx when visiting the Public IP.

Note: When we use the curl http://PUBLIC_IP inside the Jelastic environment, it loads the hello kubernetes application just fine when the IngressClassName is set to kong. However, it does not work publicly.

We would really appreciate some help on this one. Please and thank you.
