When i run test network at hyperledger fabric i have this error
rror: Post "https://localhost:7053/participation/v1/channels": dial tcp 127.0.0.1:7053: connect: connection refused
Channel creation failed
How to solve it
Renaming current folder and Re-downloading the sample worked.
Could be a issue with port or prior version
Here are details steps to cleanup prior sample which worked for me
Step 1) run following
./network.sh down
Step 2) docker ps
Validated that all containers are gone.
docker ps --all
Step 2.b) Incase if you still see containers, use following
Note the first letter of the container ID from 'docker ps --all' command
e.g 20c0e323a69 hyperledger/fabric-tools:latest
Run following
docker rm 2
it will remove 20c0e323a69
Do the same for all containers
Step 3) Renaming the folder steps
Go back to the root directory
Rename the folder by running following. or just delete if you dont have any custom scripts
$ mv fabric-samples oldfabric-samples
Step 4 ) reinstall by running following
"$ curl -sSL https://bit.ly/2ysbOFE | bash -s -- 2.2.2 1.4.9"
or follow steps in
https://hyperledger-fabric.readthedocs.io/en/release-2.2/test_network.html
Step 5) List of following command
cd fabric-samples/test-network
./network.sh down
./network.sh up
docker ps -a
Step 6)./network.sh createChannel
Above should work now
Assuming you are in the following folder
fabric-samples/test-network
Additional Learnings --under the hood
use vscode to view network.sh '$ code network.sh' and look for line scripts/createChannel.sh
if needed, navigate to scripts/createChannel.sh from vscode for more info
