How to set up a fabric network v2 on 2 machines?

Question

I am trying to set up the HLF first network on 2 vms. So, i created 2 yaml files each for every machine.

Machine 1: - 1 orderer - 2 peers - 2 couchdb - 1 ca

Machine 2: - 2 peers - 2 couchdb - 1 ca

There is no problem to fetch block 0 and i am able to create the channel and finally to install the chaincode. However, when i am trying to to approve a chaincode definition for my orgs, i receive the same error from both machines.

Error: failed to retrieve broadcast client: orderer client failed to connect to 127.0.0.1:7050: failed to create new connection: connection error: desc = "transport: error while dialing: dial tcp 127.0.0.1:7050: connect: connection refused"

P.S. Sorry about the big post i am trying to be specified in case someone can find my faults

i checked my containers:

docker logs orderer.example.com

Output:

@HectorCode, I made some changes to node1.yml file as I'm assuming that u are running both the Org1 peers on same VM hecne you can't use port 7051 for both peer0 and peer1. Similarly make changes to node2.yml based on these.

The issue is in your channel configuration file (configtx.yaml). You have defined the same ports for Anchors peers on both Organization.

Org2 (Presently):

AnchorPeers:
        - Host: peer0.org2.example.com
          Port: 7051

(Org2) Change it to :

 AnchorPeers:
            - Host: peer0.org2.example.com
              Port: 9051
