fabric-ca-client enroll with error Failed to read response of request: POST http://localhost:7054

Question

I checkout project fabric-samples and run file startFabric.sh to start Fabric blockchain network.
After that, I run node enrollAdmin.js to enroll the new admin
Now, I want to use the command line of fabric-ca-client to add a new user to org1. I execute the commands below:

1. Access to ca_peerOrg1 docker
   docker exec -it ca_peerOrg1 bash

2. I check the value of
   $FABRIC_CA_CLIENT_HOME is unset
   $FABRIC_CA_HOME is /etc/hyperledger/fabric-ca-server

3. Go to /etc/hyperledger/fabric-ca-server directory and check command
   fabric-ca-client
   
   
4. And run this command fabric-ca-client enroll -u http://admin:adminpw@localhost:7054
   But it occurs error below:

Anyone could help? Thanks for reading

I just encountered the same problem. For anyone who is interested, this error indicates fabric-ca-server is running with TLS enabled.

To get rid of this error, you need to make the following changes to the fabric-ca-client command:

• use https instead of http in the url
• use ca host name instead of localhost in the url
• provide the TLS cert file for the server's listening port via --tls.certfile

e.g. fabric-ca-client enroll -u https://admin:adminpw@ca.org0.example.com:7054 --tls.certfiles /certs/ca/ca.org0.example.com-cert.pem

The TLS cert file was generated by fabric-ca-server at startup. The default file location is $FABRIC_CA_SERVER_HOME/tls-cert.pem. Otherwise, the location is specified by $FABRIC_CA_SERVER_TLS_CERTFILE or fabric-ca-server-config.yaml
