I am trying to create a channel in the deployed hyperledger fabric.
using command
peer channel create -o orderer0.orgorderer1:7050 -c mychannel -f ./channel-artifacts/channel.tx
but i am getting error
2018-01-18 09:59:05.382 UTC [grpc] Printf -> DEBU 011 transport: http2Client.notifyError got notified that the client transport was broken read tcp 10.244.1.8:47112->10.96.99.75:7050: read: connection reset by peer.

More info
my hyperledger fabric is deployed on kubernetes. using link
And is was working fine
now i have used custom cryptographic material for the MSP
and redeployed.
And getting the above error
all the pods in the kubernestes are up and running.

I'm setting up an hyperledger fabric network with docker compose.
All the containers are up and running but i'm having problems with the appprovemyorg command.
These are the logs of the peer after joining the channel:

As you can see, i have some warnings but I can safely join the channel and I have no problems at all when i install the chaincode (the warnings disappear too).
These are the logs on the peer after installing the chaincode:

So i can't approve the chaincode and advance in the process.
Can anyone help me solve this problem?
Thanks
I am trying to setup blockchain network with two organizations having two peers in each organization. I generated crypto material using fabric-ca-server-client command after setting up separate CAs for org1, org2 and orderer organizations. All peers and orderers are running in different containers in a single VM. Issue is about IP SANS.
# Register peer0 certificates now
fabric-ca-client register --caname ca.org1.example.com --csr.cn peer0.org1.example.com --csr.names 'O=org1,OU=peer,C=IN,ST=Telangana' --id.name peer0 --id.secret peer0pw --id.type peer --id.attrs '"hf.Registrar.Roles=peer"' --tls.certfiles ${FABRIC_CA_CLIENT_HOME}/ca/tls-ca-org1-example-com-cert.pem
# Enroll peer0 certificates now which stores crypto material for peer0 in msp folder
fabric-ca-client enroll -u https://peer0:peer0pw#localhost:7060 --caname ca.org1.example.com --csr.cn peer0.org1.example.com --csr.names 'O=org1,OU=peer,C=IN,ST=Telangana' -M ${FABRIC_CA_CLIENT_HOME}/peers/peer0.org1.example.com/msp --csr.hosts peer0.org1.example.com --tls.certfiles ${FABRIC_CA_CLIENT_HOME}/ca/tls-ca-org1-example-com-cert.pem
I am getting below error while executing docker logs peer0.org1.example.com

I just up the hyperledger docker container. I use TLS enabled orderer and peers. I created the channel using the command in cli bash(for peer0)
peer channel create -o orderer0.Myname.com:7050 -c Mynamechannel -f /opt/gopath/src/github.com/hyperledger/fabric/peer/channel-artifacts/channel.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/Myname.com/orderers/orderer0.Myname.com/msp/tlscacerts/tlsca.Myname.com-cert.pem
It runs successfully. Then I try to join the channel using the command
export CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.Myname.com/users/Admin#org1.Myname.com/msp
export CORE_PEER_ADDRESS=peer0.org1.Myname.com:7051

export CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.Myname.com/peers/peer0.org1.Myname.com/tls/ca.crt
peer channel join -b Mynamechannel.block

Query
What is meant by this error? What does orderer read from cli(IP of cli: 172.19.0.7:40978) during broadcast?
It seems as though grpc is using some fairly random ports from my CLI client which I haven't manually opened.
Has anyone else had troubles with Fabric on AWS EC2 in regards to security groups and the firewalled ports? How would one create a relatively safe security group that's open enough to allow for these random grpc ports? Is there a specific port range this CLI client uses?

Ports 51502, 51518, 51522 referenced above from the orderer logs.
These errors stemmed from a CLI client issuing a ./peer chaincode instantiate command which is failing.
In my case, I got the same error until I opened all ports for outbound connections on my peers.
Try to fix rules for your peer:
