Currently, I'm building a network on Kubernetes using this repo. there were 2 worker nodes. I set up a Kube config file of AWS EKS.

When I run the command :

kubectl hlf ca register --name=${caName} --user=${user} --secret=${secret} --type=${type} \
                --enroll-id ${bootstrapUserId} --enroll-secret=${bootstrapUserSecret} --mspid ${mspId}

Getting an error which is enroll failed: enroll failed: POST failure of request: POST https://xx.xx.xx.xx:31931/enroll {"hosts":null,"certificate_request":"-----BEGIN CERTIFICATE REQUEST-----\nMIH3MIGfAgEAMBeeeeeeeeBMGByqGSM49AgEGCCqGSM49\nAwEHA0IABJkaVaotjYa3gO1Gm02VDEeiUbedgus0HKJ12xqV7a+Pu5CNNN60jNEG\nAZEpGLV9RvZu0iNnYGToH+HRCs1PJ+qgLDAqBgkqhkiG9w0BCQ4xHTAbMBkGA1Ud\nEQQSMBCCDmRvY2tlci1kZXNrdG9wMAoGCCqGSM49BAMCA0cAMEQCIAEo5t2PqeeeeeeeeTtbiJ7JQDifDDeOOCuv16AiB1ZuIjlIQ/WaylWWmh5gLTcbm3Yyzb\nGS7+9+tbIxUV1g==\n-----END CERTIFICATE REQUEST-----\n","profile":"","crl_override":"","label":"","NotBefore":"0001-01-01T00:00:00Z","NotAfter":"0001-01-01T00:00:00Z","ReturnPrecert":false,"CAName":""}: Post "https://xx.xx.xx.xx:31931/enroll": x509: certificate is valid for 127.0.0.1, xx.xx.xx.xx, not xx.xx.xx

Could anyone please tell me if our cert is stored on any server at first run and we can't access the new cert on new IP or any other issue?
