Ok but it is a simple redirect in my opinion.
My ingress address is : https://app1.kube-dev.example.com/
My Haproxy/F5 adress is : https://app1-dev.example.com/

So when user enter in web browser https://app1-dev.example.com/ shoud be redirected thru haproxy/f5 to address
https://app1.kube-dev.example.com/ and be able to see application page but we got 503.

Are you using this project ingress-nginx controller for the redirects or F5 nginx controller?

@longwuyuan can you follow up with a close if this is not needed

I have a Tanzu Cluster and installed Nginx Ingress Controller on it. F5 or Haproxy are external.

The trafic look like:
User-> Address on F5/Haproxy -> Ingress Address from Nginx Controller.-> Service - > App in Pod

After few experiments I was able to run this with haproxy ingress controller and I think the problem is with ports which are used in service and haproxy configuration:
http Listening port is 80 and Target is 8080
https Listening port 443 and Target port is 8443

Haproxy backend is set to port 443.

I don't tell anything about rest of the setup.
Configuration:
Tanzu Kubernetes Cluster - TKGs with NSX Load Balancer.

EDIT:
Additional info which can help:

I'm using Nginx with specific IP for exampler 10.1.1.10 and when try to rewrite address
https://app1.kube-dev.example.com to https://app1-dev.example.com it always point me to page which is displayed by kubernetes internal proxy : https:ingress-nginx-controller:443/proxy/

So I think I need some rule or DNS entry. I use wildcard certificate kube-dev.example.com pointing IP. 10.1.1.10 maybe this is a problem.

Can you put in a rewrite or a redirect at the haproxy level?
