Failed to update endpoint cert-manager/cert-manager-webhook

[AuqW9cQ]

I have a MicroK8s 1.24 single Node installation, cert-manager(1.8.2) deployed via helm3.

deploy my ClusterIssuer:

apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
  name: letsencrypt-staging
spec:
  acme:
    email: letsencrypt@domain.tld
    solvers:
    - selector: {}
      http01:
        ingress:
          class: public # ingress class is called public in MicroK8s, not nginx
                         # https://github.com/cert-manager/cert-manager/issues/2842
    privateKeySecretRef:
      name: letsencrypt-staging
    server: https://acme-staging-v02.api.letsencrypt.org/directory
---
apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
  name: letsencrypt-prod
spec:
  acme:
    email: letsencrypt@domain.tld
    solvers:
    - selector: {}
      http01:
        ingress:
          class: public # ingress class is called public in MicroK8s, not nginx
                         # https://github.com/cert-manager/cert-manager/issues/2842
    privateKeySecretRef:
      name: letsencrypt-prod
    server: https://acme-v02.api.letsencrypt.org/directory

Then i deploy nextcloud with the following ingress:

apiVersion: networking.k8s.io/v1 
kind: Ingress
metadata:
  name: nextcloud-ingress
  namespace: nextcloud
  annotations:
    kubernetes.io/ingress.class: "nginx"
    cert-manager.io/cluster-issuer: "letsencrypt-prod"

spec:
  tls:
  - hosts:
    - cloud.domain.tld
    secretName: nextcloud-secret
  rules:
  - host: cloud.domain.tld
    http:
      paths:
      - pathType: Prefix
        path: /
        backend:
          service:
            name: nextcloud-server
            port:
              number: 80

All thems to be good and i get a certificate:

kubectl get certificate -n nextcloud 
NAME               READY   SECRET             AGE
nextcloud-secret   True    nextcloud-secret   145m

But i cant reach my nextcloud and get a 404 error.

and this message:
cert-manager 5m15s Warning FailedToUpdateEndpoint endpoints/cert-manager-webhook Failed to update endpoint cert-manager/cert-manager-webhook: Operation cannot be fulfilled on endpoints "cert-manager-webhook": the object has been modified; please apply your changes to the latest version and try again
