I tried to do network down and then network up then sudo ./network.sh up createChannel -ca -s couchdb but I still encounter this error. Please help as I'm stuck on this.

Hi @Bobbijn the hyperledger documentations on installations and running the test network worked for me. I would like to suggest to update the documentations on Labs 2.1 and 4.1 to follow what's on hyperledger documentation. Thank you.

Hello @skyrocket55 ,

Welcome to the Developers course for Fabric. Getting the system set up correctly is imperative for success in the course.

The error you're encountering is related to a connection issue with the orderer and peer services, which suggests they might not be running or are inaccessible at the specified ports.
First, please ensure that all Docker containers for your network are up and running using the docker ps command.
If they're not running, you might need to check your Docker setup and restart.

Also, ensure there are no network conflicts, and the ports mentioned in the error messages are correctly mapped and accessible.

Additionally, double-check the configuration files for any discrepancies in the port numbers or addresses. For more detailed troubleshooting, consider revisiting the network setup instructions or consulting Hyperledger Fabric's official documentation for guidance on resolving connection issues.

Let me know if this helps, Bobbi
