I am currently doing hyperledger fabric network setup in Kubernetes. My network includes, 6 organizations and 5 orderer nodes. Our orderers are made to follow raft consensus. I have done the following:

• Setup ca and tlsca servers
• Setup ingress controller
• Generated crypto-materials for peers, orderer
• Generated channel artifacts -- Started peers and orderers

Next step is to create the channel on orderer for each orgs and join the peers in each org to the channel. I am unable to create the channel. When requesting to create the channel, getting the following error:

SERVICE UNAVAILABLE - No raft leader.

How to fix this issue??

Can anyone please guide me on this. Thanks in advance.
