Orderer connection refused Hyperledger Fabric - yaml

Question

I am trying to run the fabric-sample with tls settings removed.
The networks and all containers are running good without any errors but when I , try to run the channel creation command from cli, it is unable to connect to orderer container.

Command failing to execute-
peer channel create -o orderer.example.com:7050 -c byfn-fabric-channel -f ./channel-artifacts/channel.tx
Error:-
root#b7a8ed102a7b:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer channel create -o orderer.example.com:7050 -c byfn-fabric-channel -f ./channel-artifacts/channel.tx
Error: failed to create deliver client: orderer client failed to connect to orderer.example.com:7050: failed to create new connection: connection error: desc = "transport: error while dialing: dial tcp 172.21.0.2:7050: connect: connection refused"
Since TLS if off, certificates configuration should not be problem.Although cli container is able to ping orderer container.
But orderer on port 7050 is refusing connection, eventhough services on that port is running inside orderer.
