Cannot access service from external IP azure devops kubernetes

Question

I can obtain my service by running

$ kubectl get service <service-name> --namespace <namespace name>

NAME          TYPE           CLUSTER-IP  EXTERNAL-IP  PORT(S)       AGE
service name  LoadBalancer   *********   *********    port numbers  16h

here is my service running at kubernetes but I can't access it through public IP. below are my service and deployment files added . i am using azre devops to build and release container image to azure container registry . As you see above on service describe i got external ip and cluster ip but when i try this ip in browser or use curl i get no response. `

Apparently there's a mismatch in label and selector:

Service selector

"selector": {
      "run": "profile-management-service"

While deployment label

"labels": {
      "run": "deployment-name"
    },

Also check targetPort value of the service, it should match containerPort of your deployment
