i am able to configure hyperledger fabric and kubernetes with cli. But now i want to configure hyperledger fabric node sdk with kubernetes. I have created with files but, not able to connect it through node sdk rest endpoints.

my hyperledger services:

[ec2-user@ip-172-31-21-223 ~]$ kubectl get services --namespace=fabrick8s
NAME                   TYPE       CLUSTER-IP      EXTERNAL-IP   PORT(S)                           AGE
ca0-org1               NodePort   10.110.184.19   <none>        30101:30101/TCP,30102:30102/TCP   26h
orderer0-orgorderer1   NodePort   10.99.12.255    <none>        32000:32000/TCP                   46h
peer0-org1             NodePort   10.101.50.225   <none>        30001:30001/TCP,30002:30002/TCP   3h5m

i have added cluser ip into node network config file but i am not able to connect. getting following error:
