How do I have to configure certmanaager when using a gitlab managed cluster?

I use a scaleway kubernetes cluster v1.21.1 managed by gitlab.

To do this, I created a Cluster Management Project with the default template. https://docs.gitlab.com/ee/user/clusters/management_project_template.html (only ingress & certmanager enabled)

I only changed the email in the cert-manager yaml files.

When I call my testsite no SSL certificate is showing up.

Gitlab created following Pods (Logs):

Question

Is this a configuration issue?

Do I have to change something in the cluster configuration?
