HTTP Request header Client IP not include visitor IP

Hi, I set up traefik in Kubernetes, AWS/EKS tobe exact. I have problem getting HTTP client/visitor IP address on the header. Looks like because I am using AWS NLB as the load balancer.

Based on this URL: , some one suggesting me to enable "Proxy protocol" on both Loadbalancer and traefik. However, it still not works. I hope someone can give me more advice regarding this matter. Thanks in advance.
