Using nginx-ingress http works but https is not on selfhost kubernetes

Question

i use the nginx-ingress in my kubernetes cluster

i installed the nginx-ingress-controller successful. here is my ingress:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: demo-ingress
spec:
  ingressClassName: nginx
  rules:
    - host: demo.test.cn
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: demo-service
                port:
                  number: 443
---
apiVersion: v1
kind: Service
metadata:
  name: demo-service
spec:
  selector:
    app: hello-node
  ports:
    - port: 443 # service port
      targetPort: 8080 # container port
      protocol: TCP
    # nodePort port exposed on the host machine

• pupulate http url [http://demo.test.cn/] in browser, it works well
• populate the https url [https://demo.test.cn/] in browser, it does't work
• check the log in nginx-ingress-controller access log
