Hyperledger Composer - connection issue when using

Question

i'm having issues deploying composer on top of a multi org, multi peer network. My network has two CA's, one order and six peers (two per org).

The network uses TLS, which is giving me some issues. When running composer network ping -n network2 -p org1 -i user -s pass

i am receiving SSL errors; E0913 16:54:49.855499904 120141 ssl_transport_security.c:921] Handshake failed with fatal error SSL_ERROR_SSL: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed.

Error: Error trying to ping. Error: Error trying to query chaincode. Error: Connect Failed Command failed

Here is my connection file;

{ "type": "hlfv1", "name": "org1", "orderers": [ { "url" : "grpcs://localhost:7050", "cert" : "-----BEGIN CERTIFICATE-----removed-----END CERTIFICATE-----\n" } ], "ca": { "url": "http://localhost:7054", "name": "ca_peerOrg1", "trustedRoots": [""], "verify": true }, "peers": [ { "requestURL": "grpcs://localhost:7051", "eventURL": "grpcs://localhost:7053", "cert" : "-----BEGIN CERTIFICATE-----removed-----END CERTIFICATE-----\n" }, { "requestURL": "grpcs://localhost:8051", "eventURL": "grpcs://localhost:8053", "cert" : "-----BEGIN CERTIFICATE-----removed-----END CERTIFICATE-----\n" } ], "keyValStore": "/home/paul/.composer-credentials", "channel": "mychannel", "mspID": "Org1MSP", "timeout": "300", "globalcert": "", "maxSendSize": -1, "maxRecvSize": -1 }

The value of cert matches the contents of the .pem file used to start the CA (sh -c 'fabric-ca-server start --ca.certfile /etc/hyperledger/fabric-ca-server-config/ca.org1.example.com-cert.pem)

Any ideas how i get this working with TLS? none of the composer commands are working, they are all giving me the same errors

Answer 1

If you used cryptogen to generate your certificates then there will be tls folders for your organisations which will contain the public certificate you need to put into the connection profile. The certificate you use for the CA configuration is not the correct certificate to use.
