mdatabase.kb.io webhook error

[wid]

Hello,

I use:
Kubernetes v1.21.1
cert-manager 1.4.4

This is my configuration:
values.yaml:

enableMetricsRbac: false
dbms:
  - databaseClassName: "postgres-default"
    endpoints:
      - name: "postgres-default"
        dsn: "postgres://postgres@REDACTED"

postgres-example.yaml:

apiVersion: database.dbaas.bedag.ch/v1
kind: Database
metadata:
  name: database-sample  
spec:
  endpoint: postgres-default

I get a the following error message on kubectl apply -f postgres-example.yaml:

Error from server (InternalError): error when creating "postgres-example.yaml": Internal error occurred: failed calling webhook "mdatabase.kb.io": Post "https://kubernetes-dbaas-webhook-service.kubernetes-dbaas-system.svc:443/mutate-database-dbaas-bedag-ch-v1-database?timeout=10s": dial tcp 10.250.98.125:443: connect: connection refused
