Activate TSL for my Kubernertes Service

Hi,

I try to add TSL on my Kubernetes Service but I do not manage to make it working... I use `cert-manager` for TSL Certificate Management. I have a Service (based on FastAPI deployment) that successfully exposes port 80.

I added a CertificateIssuer and Ingress objects to my cluster but my CertificateOrder always stays in "Pending" status. I am probably missing something but I do not manage to figure out what is wrong.

Thanks for your help
