Try adding snmp-exporter with the following config manually added:


---
  ingress: 
    enabled: "true"
    hosts:
      - snmp-exporter.k8s.leb.memhamwan.net
    annotations:
      kubernetes.io/tls-acme: "true"
      kubernetes.io/ingress.class: nginx
      cert-manager.io/cluster-issuer: letsencrypt-prod
    tls:
      - secretName: snmp-exporter-tls
        hosts:
          - snmp-exporter.k8s.leb.memhamwan.net
