Connection timedout when attempting to access any service in kubernetes - deployment

Question

I've create a deployment and a service and deployed them using kubernetes, and when i tried to access them by curl, always i got a connection timed out error.
Here's my yml files:
Deployment.yml
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
labels:
app: locations-service
name: locations-service
namespace: default
spec:
replicas: 2
selector:
matchLabels:
app: locations-service
template:
metadata:
labels:
app: locations-service
spec:
containers:
- image: dropwizard:latest
imagePullPolicy: Never # just for testing!
name: locations-service
ports:
- containerPort: 8080
protocol: TCP
name: app-port
- containerPort: 8081
protocol: TCP
name: admin-port
resources: {}
dnsPolicy: ClusterFirst
restartPolicy: Always
schedulerName: default-scheduler
Service.yml
apiVersion: v1
kind: Service
metadata:
labels:
app: locations-service
name: locations-service
namespace: default
spec:
type: NodePort
externalTrafficPolicy: Cluster
ports:
- name: "8080"
port: 8080
targetPort: 8080
protocol: TCP
- name: "8081"
port: 8081
targetPort: 8081
protocol: TCP
selector:
app: locations-service
Also i tried to add ingress routes, and tried to hit them but still the same problem occur.
Note that the application is successfully deployed, and i can check the logs from k8s dashboard
Another example, i have the following svc
kubectl describe service webapp1-svc
Name: webapp1-svc
Namespace: default
Labels: app=webapp1
Annotations: <none>
Selector: app=webapp1
Type: NodePort
IP: 10.0.0.219
Port: <unset> 80/TCP
TargetPort: 80/TCP
NodePort: <unset> 30080/TCP
Endpoints: 172.17.0.4:80
Session Affinity: None
External Traffic Policy: Cluster
Events: <none>
and tried to access it using
curl -v 10.0.0.219:30080
* Rebuilt URL to: 10.0.0.219:30080/
* Trying 10.0.0.219...
