My route doesn't work on Hetzner Loadbalancer and Kubernetes

[yaser-aibees]

I have a domain on Cloudflare and let's call it example.com. On Cloudflare I enabled SSL and it is on Full mode. There is a subdomain called 'log' which points to a standalone Kong Gateway OSS instance. On Kong server I defined a service Gateway with these configs:

• name: log-service
• protocol: https
• host:
• port: 30012

Port 30012 is for ingress-nginx which has been deployed on Kubernetes and is NodePorted on my cluster. Hetzner Loadbalancer and Kubernetes nodes are inside a private network with 172.16.1.0/24 address and on my loadbalancer on Hetzner I can see the healthchecks work fine.

I also defined a route on Kong as bellow:

• name: log-route
• service: log-service
• protocol: HTTP/HTTPS
• hosts: log.example.com

Also I have enabled ACME plugin on Kong and I can see that a certificate has been issued for log.example.com domain.

With this configuration when I hit the log.example.com I get 404 Not Found error !!! I should mention that the same configurations works when I replace Kong with and nginx server and proxy_pass to Hetzner loadbalancer on port 30012. So I don't think there is a problem on Hetzner or my Kubernetes cluster, rather than with Kong Gateway itself.

What might be the problem?
