Getting an error certificate signed by unknown authority

问题

I am trying the "Deploying a Hyperledger Composer blockchain business network to Hyperledger Fabric (multiple organizations)" tutorial and I am stuck at the composer network ping stuff. The ping commands fails giving this error "Error: Error trying to ping. Error: Error trying to query business network. Error: Failed to deserialize creator identity, err The supplied identity is not valid, Verify() returned x509: certificate signed by unknown authority".

I am trying with "tls disabled" flag for peers and orderer. Also I am trying a multivm setup where orderer, org1 and org2 are running on separate vms. And I am using composer version 0.16.2 and hyperledger fabric version 1.0.4.

Any idea on this?
