I'm beginning with kubernetes and docker and facing an issue.

Deployed a springboot app on minikube after converting it to docker image (using minikube's docker)... the app is online and receiving request so well as you can see in the below screenshots, but doesn't reply as expected.

For example, when i deploy the app normally (on my computer like usually) everything works well i can go on all html pages etc, but once deployed inside minikube it doesn't reply correctly. (all working part is the receiving of favicon of spring)

YAMLs used to deploy the app:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: esse-deployment-1
  labels:
    app: esse
spec:
  replicas: 1
  selector:
    matchLabels:
      app: esse-1
  template:

        env: 
          - name: MYSQL_ROOT_PASSWORD
            value: esse_password
