Error in Composer Identity Request - hyperledger-composer

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?

it looks like the Fabric CA server container on port 7054 is not started or is not listening, or not bound to that address/port.

Can't connect to external API using Laravel Sail

The project was working fine, suddenly I couldn't connection to Stripe nor Mailtrap APIs.
Stripe error
Could not connect to Stripe (https://api.stripe.com/v1/setup_intents). Please check your internet connection and try again. If this problem persists, you should check Stripe's service status at https://twitter.com/stripestatus, or let us know at support#stripe.com. (Network error [errno 6]: Could not resolve host: api.stripe.com)
Mailtrap error
Connection could not be established with host "smtp.mailtrap.io:587": stream_socket_client(): php_network_getaddresses: getaddrinfo for smtp.mailtrap.io failed: Temporary failure in name resolution
I tried to delete the containers and build them again with --no-cache
sail down -v
sail build --no-cache
But I got an error running apt-get commands because it can't reach to the endpoint.

Error trying to start business network. Last error was Error: Error: 14 UNAVAILABLE: Trying to connect an http1.x server

Hi I am trying to run developer tutorial on hyperledger-composer from https://hyperledger.github.io/composer/latest/tutorials/developer-tutorial.html
I have setup the development environment successfully.
I receive the following error
Error trying to start business network. Error: Unable to initalize
channel. Attempted to contact 1 Peers. Last error was Error: Error: 14
UNAVAILABLE: Trying to connect an http1.x server
while I run the following command
composer network start --networkName tutorial-network --networkVersion
0.0.1 --networkAdmin admin --networkAdminEnrollSecret adminpw --card
PeerAdmin#hlfv1 --file networkadmin.card
I have checked the fabric is running and is listening to business network archive
"Listing Business Network Archive from tutorial-network#0.0.1.bna

Name:tutorial-network
Version:0.0.1

P.S I am behind firewall/proxy

How do I resolve the following issue on hyperledger composer cli command for identity issue?

image 1 image 2
From the following link
https://hyperledger.github.io/composer/reference/composer.identity.issue.html
composer identity issue -c admin#mron-business-network -fsupplier -u suppid -a "resource:org.mron.Supplier#S001" -x false
Issue identity and create Network Card for: suppid
✖ Issuing identity. This may take a few seconds...
Error: fabric-ca request register failed with errors [[{"code":400,"message":"Authorization failure"}]]
Command failed
same message posted on Rocketchat earlier. It would appear that the admin id in your card is not the one currently known to the CA server. After import using (for example) composer card import -f <filename>, you need to connect to the business network (or use composer network ping -c admin#mron-business-network to connect) - for the credentials (key/certificate) to be downloaded to the wallet from the CA server. You can then verify this with a composer card list --name admin#mron-business-network and see the 'Credentials set' message for the card in question.

How to start the Composer REST Server with the identity created through REST API?

I have configured my local REST server to use GitHub auth and Mongo DB. I have followed the deployment steps and can authenticate my GiHub ID putting the default Wallet into the Mongo DB. I then create a participant and issue an identity for that participant. I add the identity to the wallet and set that identity as the default. I was able to do a system/ping to return the current participant and also was able to call REST APIs.
Now I would like to start REST server with single user mode with identity which I created in the deployment steps as follow.
composer-rest-server -i nomura -s twidKDZiYFGw -m false -a false
I assume Blockchain identity specified on the command line at startup is created when issuing an identity for the participant.
But it shows the following error.
Discovering types from business network definition ...
Connection fails: Error: Error trying to ping. Error: Error trying to query chaincode. Error: chaincode error (status: 500, message: Error: The current identity has not been registered:nomura)
It will be retried for the next request.

Error: Error trying to ping. Error: Error trying to query chaincode. Error: chaincode error (status: 500, message: Error: The current identity has not been registered:nomura)
What else do I have to do to create valid blockchain id for starting REST server?
your identity is fine. The problem appears to be how you're trying to start the REST server. You need to specify the connection profile (to connect to the business network).
Example syntax (where 'hlfv1' below is my HL Fabric v1 connection profile name) is:
composer-rest-server -p hlfv1 -n my-network -i nomura -s twidKDZiYFGw -m false -a false

[Error: EACCES: permission denied, open '/home/ubuntu/.hfc-key-store/

I am getting following error while running composer rest server. I am using aws ubuntu 16.04 server.

To restart the REST server using the same options, issue the following command:
composer-rest-server -p hlfv1 -n digitalproperty-network -i admin -s Xurw3yU9zI0l -N never

when connecting to the running v1.0 Fabric dev environment using hlfv1 or running the REST server (as shown above) - you need to provide the default admin password of 'adminpw' - please try running composer-rest-server again and use the correct password. cheers Paul
On the similar set up, I could able to work with following command, basically use PeerAdmin user instead of admin. For example:
composer-rest-server -p hlfv1 -n my-network -i PeerAdmin -s PeerAdmin -N never
If you still face same issue, try with sudo
