I'm trying to access my website by pointing to domain.coom instead of www.domain.com using the base domain instead of subdomain.

Whenever I use sub-domain it works fine, but when I switch to base domain it points to default backend.

Ingress with subdomain:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: web-ingress
  namespace: th3-website
  labels:
    app: web
    environment: prod
spec:
  rules:
    - host: www.domain.com
      http:
        paths:
          - backend:
              serviceName: web-service
              servicePort: 80

and result with curl:

HTTP/1.1 302 Found
Content-Type: text/html; charset=UTF-8
Date: Tue, 26 Nov 2019 21:34:24 GMT
Location: /talent

X-Powered-By: PHP/7.2.25
Connection: keep-alive

But when I switch to base domain:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: web-ingress
  namespace: th3-website
  labels:
    app: web
    environment: prod
spec:
  rules:
    - host: domain.com
      http:
        paths:
          - backend:
              serviceName: web-service
              servicePort: 80

result with curl (curl -I domain.com):

result with curl (curl -I domain.com/talent):

How can I use my base domain instead of sub domain alongside with some other services that uses sub domain?

Trying to find a way but to no avail, any help is appreciated! here is my ingress controller log if it might help:
