  <p>However, refused error occurred while linking service.</p>
  
  <p>Below is my service yaml. I configured NodePort to receive service requests from outside</p>
  
  <pre><code>apiVersion: v1
  kind: Service
  metadata:
    name: apigw-nodeport
  spec:
    type: NodePort
    ports:
        - name: port-apigw
          port: 80      
          targetPort: 8001

  <p>The status of the pod and the state of svc are as follows:</p>
  
  <pre><code>al8-1@al8-1:~/kuber_test/pod_nginx$ kubectl get pods -o wide

  </code></pre>
  
  <p>When I tried to curl the nodePort to see if it was normally open, the following error occurred:</p>
  
  <pre><code>al8-1@al8-1:~/kuber_test/pod_nginx$ curl 192.168.xx.xx:31050
  curl: (7) Failed to connect to 192.168.xx.xx port 31050: connection refuesd
  </code></pre>
  
  <p>I don't know how to solve it now. </p>
  
  <p>Please let me know if there is another way to solve "CrashLoopBackOff" or how can I resolve "Connection refused"?</p>
