Hyperledger Fabric Explorer config.json handshake error

Question

Hi guys I'm using Hyperledger Fabric network and Blockchain explorer. I tested explorer for "first-network" and I succeeded. After that because I wanted to build multi-machine Fabric network, I referred to https://medium.com/@wahabjawed/hyperledger-fabric-on-multiple-hosts-a33b08ef24f And to do the test I ran all docker container(CA, ORDERER, 2PEERS, CLI) into local machine and edited config.json file as below

And I got error. there is error log below

Is there anybody who knows how to solve this problem?

Answer 1

I was facing the same problem as you post when I tried to connect Hyperledger Explorer to basic-network example.

I found this post in link below and it can solve my problem, hope it can help you too.

Unable to setup hyperledger explorer with one node (like basic network example)
