Digital Ocean Kubernetes one load balancer for two different namespaces - kubernetes

Question

I have an small kubernetes (3 small nodes) on Digital Ocean. I already configured production an it is working, but for development purposes I want to create a second environment (staging).
I have been working on and almost everything is working, but I can't get the network to work.
For example, I own the domain example.com
production will run on www.example.com and api.example.com. Then I have staging on a different kubernetes namespace staging-www.example.com and staging-api.example.com.
The only thing that this two environments are sharing are the load balancer. The issue I am facing is I cant go to staging-www.example.com and staging-api.example.com. I misconfigured something, I am trying to reach where is the misconfiguration
These two files are the ones I have for staging / ingress / network. As I wrote, for production is working, but there is something wrong for staging and I couldn't get where is the problem
