Hi, I started the official course about Hyperledger Fabric Developer, but when I run
./network.sh up createChannel -ca -s couchdb
I get the following error:
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
I am running it from Ubuntu 20.04 in WSL2 (Windows).
Did anybody already face this problem? Any idea how to fix it?
Thank you!

OK never mind I found the cause. The instructions say to run ./network.sh up createChannel -ca -s couchdb, but instead I tried to run first ./network.sh up and then ./network.sh createChannel -ca -s couchdb.
Hi, I am getting the exact same error, but unfortunately it wasn't resolved by running the "up" and "createChannel" commands separately. If anyone has any ideas then please let me know.
@drcirculor,
Hello, Let's see if we can figure this out. This error usually occurs when one of the dependencies is out of sync. Please go back and check the versions of the dependencies, especially Docker. Let me know if this helps. Bobbi
Yes, you were right - I noticed this error when I brought up the network, "Local fabric binaries and docker images are out of sync."
I ended up deleting the "fabric" and "fabric-samples" folders from "~/go/src/github.com/hyperledger", then repeating the curl and git steps in the "Hyperledger Fabric samples, binaries, and Docker images" section.
The network startup and channel creation worked fine after that.
Thanks for your help.
I am still having this issue:
- My installation is on stand alone machine.- running Ubuntu 20.04.4
I have verified the dependencies (we can add versions here) and running the correct command, but
- docker --version
Docker version 20.10.13, build a224086
- docker-compose --version
docker-compose version 1.25.0, build unknown
For the last step, (running as a root)
cd ~/go/src/github.com/hyperledger/fabric-samples/test-network/
./network.sh up createChannel -ca -s couchdb
Creating channel 'mychannel'.
If network is not up, starting nodes with CLI timeout of '5' tries and CLI delay of '3' seconds and using database 'couchdb

Earlier, I took out "name: fabric_test" from docker/docker-compose-ca.yaml file, it was complaining about name field
@farukansari i also faced the similar issue and i resolved it by applying below changes in docker-compose yaml files
