I am working on an application, which is running on nginx ingress. I'd like to be able to provision a shared SSL certificate for all of the subdomains running that application.

For this purpose I have used, Wildcard certificate with Let's Encrypt and Cert manager. After all the steup, I get my certificate to be true and my sub domains defined in a ingress resource file have a valid certificate.

But when I define an extra ingress resource file with more subdomains, they do not get a valid certificate.

Is there any limitation for one ingress file for one wildcard certificate?

Cert-manager version: 1.0.4 Kubernetes version: 1.16
