Nodeport works but ingress doesn't

i am new to kubernetes and i am tring to settup a web app for production i tested an nginx app 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. know that i deleted all nginx app deployment and service and ingress but my web app still the same(WORK via NODEPORT AND NOT via INGRESS) any help getting this to work, i am confused thanks

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