Cert-Manager does not issue a certificate

I have been trying to deploy a cluster with nextcloud following this guide from DO

How to Set Up an Nginx Ingress with Cert-Manager on DigitalOcean Kubernetes

I get to a point where I can get HTTP working with dns pointed to EXTERNAL-IP, but when I try to roll out production issuer it gets stuck in the following state

And my service has a Kubernetes Ingress Controller Fake Certificate

I can’t pass through this step
