Lab 2.1: Fail to 'Spin up the network'
After setup the environment, tried to spin up the test network, when ran './network.sh up createChannel -ca -s couchdb', got the following error:
- peer channel create -o localhost:7050 -c mychannel --ordererTLSHostnameOverride orderer.example.com -f ./channel-artifacts/mychannel.tx --outputBlock ./channel-artifacts/mychannel.block --tls --cafile /home/ubuntu/go/src/github.com/hyperledger/fabric-samples/test-network/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
- res=1
Error: failed to create deliver client for orderer: orderer client failed to connect to localhost:7050: failed to create new connection: connection error: desc = "transport: error while dialing: dial tcp 127.0.0.1:7050: connect: connection refused"
Channel creation failed
Anyone could give me clue?
Thanks!

Hi Collin. I think I had a similar issue as you. What docker-compose version are you using? I was using version 2 but i downgraded to docker-compose v1 and then this worked for me as expected.

My version is latest one. Not sure if your solution is good for me. The weird thing is, after initial installation, everything worked well. The issue happened after I ran a few applications and clean network artifacts.

Hi @Bobbijn ,
Thank you,In my case, I'm using remote VPS in the cloud running Ubuntu 20.04, and there was an issue with the user's permission. my solution was after resolving the main cause by granting privilege to the user, it was necessary to call "./network.sh down" before going to start the test network.
