Hyperledger Fabric Cant create channel on peer

Question

 I want to create the channel using command as follows:

export FABRIC_CFG_PATH=$PWD
export CHANNEL_NAME=my_channel
export CORE_PEER_LOCALMSPID="Org1MSP"

export CORE_PEER_TLS_ROOTCERT_FILE=crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt

export CORE_PEER_MSPCONFIGPATH=crypto-config/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp

export CORE_PEER_ADDRESS=127.0.0.1:7001

peer channel create -o 127.0.0.1:7040 -c $CHANNEL_NAME -f channel-artifacts/channel.tx --tls true --cafile $ORDERER_CA >&log.txt

I am getting this error:

Error: Error connecting due to  rpc error: code = Internal desc = connection error: desc = "transport: authentication handshake failed: x509: cannot validate certificate for 127.0.0.1 because it doesn't contain any IP SANs"

Answer 1

Add host entries to your /etc/hosts should resolve your issue:

127.0.0.1       localhost orderer peer0.org1.example.com peer0.org2.example.com

And then make sure to use the hostnames rather than IP addresses:

export FABRIC_CFG_PATH=$PWD
export CHANNEL_NAME=my_channel
export CORE_PEER_LOCALMSPID="Org1MSP"

export CORE_PEER_TLS_ROOTCERT_FILE=crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt

export CORE_PEER_MSPCONFIGPATH=crypto-config/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp

export CORE_PEER_ADDRESS=peer0.org1.example.com:7001

peer channel create -o orderer:7040 -c $CHANNEL_NAME -f channel-artifacts/channel.tx --tls true --cafile $ORDERER_CA >&log.txt
