Nodeport works but ingress doesn't

Question

I am new to kubernetes and I am trying to set up a web app for production. I tested an nginx app and it works perfectly in both nodeport and ingress. When I setupped my web app exposing it using nodeport it works but when I expose it via ingress it doesn't work. I know that I deleted all nginx app deployment and service and ingress but my web app is still the same (WORK via NODEPORT AND NOT via INGRESS). Any help getting this to work is appreciated.

THIS IS THE NGINX YAML CODE (WORK via BOTH NODEPORT AND INGRESS)
