Following is my ngnix template which is working fine:

enterapiVersion: networking.k8s.io/v1   
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
    nginx.ingress.kubernetes.io/proxy-body-size: "15m"
    nginx.ingress.kubernetes.io/configuration-snippet: |
        set $a $http_x_correlation_id;
        set $my_header $request_id;
        proxy_set_header X_Correlation_Id $my_header;   
        rewrite ^/app-name(/|$)(.*) /$2 break;
  name: rtfp-ingress-template
  namespace: rtfp
spec:
  ingressClassName: rtf-nginx
 rules:
  - host: ap.abc.com
    http:
      paths:
      - path: /app-name
        pathType: ImplementationSpecific
        backend:
          service:
            name: service
            port:
              number: 80

But as soon as i introduce a if statement to optionally add header ie. if its not coming from client then header should be added, it fails with 404

nginx.ingress.kubernetes.io/configuration-snippet: |
        set $a $http_x_correlation_id;
        if ($a = ''){
            set $my_header $request_id;
            proxy_set_header X_Correlation_Id $my_header;           
        }        
        rewrite ^/app-name(/|$)(.*) /$2 break;

If this is not possible via configuration-snippet, please let me know what are the steps to achieve it via lua script and any good tutorial for lua script in an ngnix kubernetes environment.

Please see an error when clients attempt to upload images to the endpoint https://prod.example.net.au:9433/

I am not sure it is related but we had renewed the SSL certificate and changed from a wild card SSL certificate *.example.net.au to prod.example.net.au It may be at the client end also...
Would you advise where the problem may be?

One of client Message when trasferring images to us:

24/01/2019 8:01 PM Error Unable to upload images after 3 attempts. System.ServiceModel.CommunicationException: An error occurred while making the HTTP request to https://prod.example.net.au:9433/. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case.
This could also be caused by a mismatch of the security binding between the client and the server. 

---> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send.  
---> System.IO.IOException: Authentication failed because the remote party has closed the transport stream.
