The connection to the server is lost

When I run kubectl get node ,I am getting this:The connection to the server is lost localhost:8080 was refused - did you specify the right host or port?
how can I fix this

Kafka configuration

Hi, thanks for the detailed configuration steps, however I'm having some issues setting up Kafka. Are you running Kafka inside Kubernetes? If yes, would you mind sharing the config files? Thanks!

"password": "string",
"affiliation": "string",
"roles": "string"
}

Error during Chain Code Instantiate

Chaincode Instantiate fails with failed to invoke chaincode name:"lscc" , error: timeout expired while starting chaincode rtrcc:1.0 for transaction.

I made a simplified model with one org one peer and one orderer.I have 2 k8s nodes
I am able to launch orderer and peer pods , create channel , fetch blocks , install chaincode.
But above error comes up during chain code instantiate.
Chaincode Image gets created in one of the nodes.
I can see docker container build on one of my nodes using docker ps -a but it gets removed quickly.
Instantiate hangs for about 10 minutes or more before throeing this error in CLI

Error: could not assemble transaction, err proposal response was not successful, error code 500,
msg timeout expired while starting chaincode rtrcc:1.0 for transaction

Looks like the chain code containers is not able to reach k8s pods.
