Kubernetes service created via exposed deployment is not responding to curl - kubernetes

Question

I deployed my application using deployment construct. State of my pod is Running and making curl against pod's IP returns application content. However when I created service using kubectl expose deployment and I curl service's IP then curl throws Connection refused error. Why is that?
My pod
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
cge-frontend-5d4595469b-qvcsd 0/1 Running 0 19s 10.40.0.4 compute04 <none> <none>
My service
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
cge-frontend ClusterIP 10.98.212.184 <none> 80/TCP 16m
Error
$ curl 10.98.212.184
curl: (7) Failed connect to 10.98.212.184:80; Connection refused

Answer 1

After investigating my service with kubectl describe svc command. I fogure out that my service has no Endpoints - endpoints section should list pod's IP.
$ kubectl describe svc cge-frontend
Name: cge-frontend
Namespace: default
Labels: app=cge-frontend
Annotations: <none>
Selector: app=cge-frontend
Type: ClusterIP
IP: 10.98.212.184
Port: <unset> 80/TCP
TargetPort: 80/TCP
Endpoints:
Session Affinity: None
It turned out that, the error was caused by one of my probe that was keeping my pod in Running state but not in Readystate. Fixing probes, fixed my pods, and that fixed the service.
My pod after fixing probes is now in correct state READY 1/1
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
cge-frontend-5d4595469b-qvcsd 1/1 Running 0 19s 10.40.0.5 compute04 <none> <none>
