Error reading secret/**: Get http://**:8200/v1/secret/**:

When I am trying to to read secret i get request cancelled and the below error. Its happening only in the kube pod, but the request if successful in host machine of kubernetes.
net/http: request canceled (Client.Timeout exceeded while awaiting headers)
Step: 1
./vault write --address=http://:8200 auth/approle/login role_id= secret_id=**
This is working
Step: 2
export VAULT_ADDR=http://:8200
Step: 3
./vault kv get secret/

This is throwing error connection timeout.
I looked at audit logs and response is correct for the above request. But the response is not reaching till the pod
