Custom certificate not working

[pacmanmulet]

Report

We are encountering an error when using our own certificate.

Expected Behavior
kubectl get --raw "/apis/external.metrics.k8s.io/v1beta1" works as usual

Actual Behavior
"Error from server (ServiceUnavailable): the server is currently unable to handle the request"

Steps to reproduce the problem
Generate ca and cert files
Create kedaorg-certs secret
Install Keda to your cluster (Using 2.14.2 chart version) disabling certs:

certificates:
  autoGenerated: false

KEDA version
2.14.0

Kubernetes Version
1.27.0

Executing the next patch solves the problem, but I suppose it is not the right way:
oc patch apiservice v1beta1.external.metrics.k8s.io -p '{"spec": {"insecureSkipTLSVerify": true}}'

Are steps right or there any other requirements for using your own certificate?

Thanks.
