title: Error starting Business network application in Hyperledger fabric composer-- Multi host peer environment
body: <p>I'm creating a fabric network with 5 peers. </p>
  
  <p>2 peers, CA and orderer running on machine 1,
   1 peer and couch instance on machine 2,
   1 peer and couch instance on machine 3,
   1 peer and couch instance on machine 4.</p>
  
  <p>They all are on the same channel. I was able to install the .bna into the network. But when I tried starting the application using composer tool, using the below command</p>
  
  <p><strong>"composer network start -c PeerAdmin@hlfv1 -n blockv6 -V 0.0.1  -A admin -S adminpw"</strong></p>
  
  <p>I'm getting no valid response error</p>
  
  <p>✖ Starting business network definition. This may take a minute...
