Ingress – default backend – 404 on TLS – Nginx

I’m using Rancher 2.4.7 to deploy applications on customer’s environments.
I successfully created a new cluster for a production environment however whenever I create an Ingress resource with a specific hostname (the certificate is valid) : I get the default backend - 404 message when accessing my applications.

If I create an Ingress resource using the embed xip.io hostname, I can access my applications like it’s supposed to.

I tried creating my resource using kubectl and the Rancher UI.

When getting the default backend - 404 error, no logs are registered on my deployment.

Any thoughts what is wrong?

EDIT:

I’m using nginx-ingress shipped with Rancher. I’m not using any Cloud Provider. I installed a RKE Cluster using the Rancher UI.

    I am not sure if I am able to understand since it would require some RnD.
    Meanwhile, you can checkout the ingress config that I used on my project :

    Note: What version of Ingress I used and also the annotations for it

    apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: ingress-service
  annotations:
    nginx.ingress.kubernetes.io/default-backend: ingress-nginx-controller
    ## tells ingress to check for regex in the config file
    nginx.ingress.kubernetes.io/use-regex: "true"
    cert-manager.io/cluster-issuer: "letsencrypt-prod"
    nginx.ingress.kubernetes.io/configuration-snippet: |
      add_header Access-Control-Allow-Methods "POST, GET, OPTIONS";
      add_header Access-Control-Allow-Credentials true;
    nginx.ingress.kubernetes.io/enable-cors: "true"
    nginx.ingress.kubernetes.io/cors-allow-methods: "PUT, GET, POST, OPTIONS"
    nginx.ingress.kubernetes.io/from-to-www-redirect: "true"  ## IMPORTANT

spec:
  ## TLS config
  tls:
    - hosts:
        - www.mydomain.com
        - mydomain.com
      secretName: cultor-test-tls
  ## our custom routing rules
  rules:
    - host: www.mydomain.com
      http:
        paths:
          - path: /api/upload/?(.*)
            backend:
              serviceName: aws-srv
              servicePort: 3000
          - path: /api/project/?(.*)
            backend:
              serviceName: project-srv
              servicePort: 3000
          - path: /api/profile/?(.*)
            backend:
              serviceName: profile-srv
              servicePort: 3000
          - path: /api/users/?(.*)
            backend:
              serviceName: auth-srv
              servicePort: 3000
          - path: /?(.*)
            backend:
              serviceName: client-srv
              servicePort: 3000

    Important

    Make sure you’ve tried accessing the domain with and without WWW and add this in your config as shown above

        nginx.ingress.kubernetes.io/from-to-www-redirect: "true"

    Your service and deployment labels are not matching. That’s why any of the requests for this service are not finding the backend and there is nothing to respond to these requests. For service you use:

    selector:
    name: nginx

    When for deployment you use:

      labels:
    app: nginx

    You have to change labels in either of the deployment so they will match.
