<!-- end snippet -->
I am trying to create a network with 5 orgs.
1)Able to successfully create the crypto-config files
2) Channel artifacts are created successfully
3) Channel transaction is created successfully
4) Anchor peer transactions are created successfully
5) Created channel successfully
6) peer 0 of the first org is able to join the channel
But when peer 1 of first is trying to join the channel, getting the below error. What can be the reason.
******Error: error getting endorser client for channel: endorser client failed to connect to peer1.reliancecapital.reliance-network.com:8051: failed to create new connection: connection error: desc = "transport: error while dialing: dial tcp 192.168.64.12:8051: connect: connection refused"******

Answer 1

I don't know if this is still relevant, but you seem to have a DNS resolution problem on your hands. If you're launching this setup via docker-composer, then you might want to modify your /etc/host to route requests for peer1.reliancecapital.reliance-network.com to your localhost.
You can also statically bind peer1.reliancecapital.reliance-network.com to your machine's IP via the extra_hosts option in your docker-compose file. Also make sure that all your peers are in the same docker network.
