Not able to access this NodePort service outside the cluster (in browser)

Question

I am learning K8s and the NodePort service is returning me timeout error while accessing it from outside the cluster. Inside the cluster it works alright. I have Minikube using docker driver.

I created the following deployment:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: sample-python-app
  labels:
    app: sample-python-app
spec:
  replicas: 2
  selector:
    matchLabels:
      app: sample-python-app
  template:
    metadata:
      labels:
        app: sample-python-app
    spec:
      containers:
      - name: python-app
        image: abhishekf5/python-sample-app-demo:v1
        ports:
        - containerPort: 8000

and the service.yml is as follows:

apiVersion: v1
kind: Service
metadata:
  name: python-django-app-service
spec:
  type: NodePort
  selector:
    app: sample-python-app
  ports:
    - port: 80
      targetPort: 8000
      nodePort: 30007

Now when I try to access it inside the cluster, it works just fine:

minikube ssh
curl -L http://<cluster ip>:80/demo

But as soon as I hit the following outside the cluster, it times out:

curl -L http://<minikube ip>:30007/demo //Using -L because the app requires a redirect to work//

This is the python django app that I'm trying to access (Docker file is in the github repo only):

Python app

This post didn't help me either.

What am I doing wrong here?
