When I make a request for identity in composer, always give this error:
composer identity request -c PeerAdmin@orgx-network-xxx -u admin -s adminpw -d alice
Error: failed to request identity. Error trying to enroll user and return certificates. Error: Calling enrollment endpoint failed with error [Error: connect ECONNREFUSED 127.0.0.1:7054]
What can cause this and how can I solve it?
