Hi. Which Operating system are you using?
Hi @Karan, I am using Ubuntu 14

@digger. Try disabling the firewall before running your command:

$ sudo ufw disable

The default port is 7051 but you have set it to 8051.

export CORE_PEER_ADDRESS=peer1.org1.example.com:8051

Try changing it to 7051 and see if it works.

export CORE_PEER_ADDRESS=peer1.org1.example.com:7051


Hope this helps!

Turn down the network, Generate the necessary files and then turn the network back on. 

./byfn down
./byfn generate
./byfn up

Open the hosts file:

$ gedit /etc/hosts

And add the IP address of the system than contains the channel. Save and exit the file and then run your command. It worked for me.

Hello John,

I'm facing the same issue, can you be more precise on what we have to write inside that file ? In my case my channel in created on the cli container, what should I write in this case ?

Thank you,

Elias

Find the IP address of the system that contains the cli container using the below command:

$ ifconfig

Then open the /etc/hosts file:

$ gedit /etc/hosts

and then add the IP address in that file.
