Hyperledger Composer How to specify server name in composer connection profile

Question

When I specify orderer and peer host name (e.g. peer0.org1.example.com) in /etc/hosts file, "composer" command works.

But, if I specify server's IP address, it does not work.

$ composer network list -p hlfv1 -n info-share-bc -i PeerAdmin -s secret

✖ List business network info-share-bc
Error trying to ping. Error: Error trying to query chaincode. Error: Connect Failed

Command succeeded

This is a command example when I specify host name in /etc/hosts.

$ composer network list -p hlfv1 -n info-share-bc -i PeerAdmin -s secret

✔ List business network info-share-bc
name:       info-share-bc
models: 
  - org.hyperledger.composer.system
  - bc.share.info

To solve this problem you can use the hostnameOverride option in connection profile.

 "eventURL": "grpcs://<target-host>:17053", 
 "hostnameOverride": "peer0.org1.example.com",
