Waiting for HTTP-01 challenge propagation: failed to perform self check GET request

Hi Dears,
Hi Dears,
I really appreciate it if somebody gives me a solution to this. I am sticking with one issue for almost two weeks, I am trying to have cert in Kubernetes and i followed exactly like the example but always get issues as Waiting for HTTP-01 challenge propagation: failed to perform self-check GET request. Can somebody help me, please?
here is some info:
Let me explain to you the setup: we have bare-metal Kubernetes (Kubespray) where we have metallb loadbalancer assign ip address and NGINX ingress controller with a grabbed IP address from metallb. As IP address is not public, we mapped to an public IP address therefore our x.x.x.x nginx controller ip mapped to y.y.y.y with opened 80 and 443 ports.
Then i created cert-manager-v1.8.2 already checked all pods up and running. Then create two staging and production as following:
apiVersion: cert-manager.io/v1
kind: ClusterIssuer
name: letsencrypt-staging
email: sarang.kahva@gmail.com
server: https://acme-staging-v02.api.letsencrypt.org/directory
name: letsencrypt-staging-private-key
