Certbot cannot renew in k8s

Hi all,
I have K8S cluster bare-metal , installing by kubeadm , with metallb, ingress-nginx.
This is my web app ingress

apiVersion: networking.k8s.io/v1
kind: Ingress
  name: web-ingress
  namespace: web
    kubernetes.io/ingress.class: "nginx"
    cert-manager.io/cluster-issuer: letsencrypt-production
    cert-manager.io/acme-challenge-type: http01
    acme.cert-manager.io/http01-edit-in-place: "true"
    nginx.ingress.kubernetes.io/force-ssl-redirect: "true"
  - hosts:
      - web.com.vn
    secretName: web-tls
  - host: web.com.vn
      - path: /
        pathType: Prefix
            name: web-svc
              number: 80

It used to worked fine, I had let’s encrypt cert for my web app 2 months ago.
Today I receive an email about my web app cert will expire in 19 days, so I start to troubleshoot why certbot cannot renew my web app cert.

From my computer I can

curl http://web.com.vn/.well-known/acme-challenge/38G9DdwdnaLlLLuDUFtAc9_ZHI9saEVdyDEU0J2BG64

Please give me some advice, thank you very much.

After delete and create all resources (deployment,service,ingress,secret…) many times, my web app can get let’s encrypt cert successfully.
Maybe because my web app is too old (nginx+php5.3)
Other (newer) apps in my k8s work just fine with let’s encrypt + nginx ingress.
