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
Identifier:tutorial-network#0.0.1
Name:tutorial-network
Version:0.0.1
Command succeeded"
P.S I am behind firewall/proxy
Configuration
Node #8.11.3
composer #0.19
Mac OS High Sierra

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.

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.
After the update to 0.14, I am no more able to connect to the chain from the cli
composer network ping -p hlfv1 -n basic-sample-network -i admin -s adminpw
or
composer-rest-server -p hlfv1 -n basic-sample-network -i admin -s adminpw -N never
I have the following error
Error: Error trying to ping. Error: Error trying to query business network.
Error: chaincode error (status: 500, message: Error: The current identity has not been registered: admin)
All composer component were updated to 0.14, and the test was made with basic-sample-network. For information, npm test on this exemple was perfectly.
OS: Ubuntu
Please confirm that you have read the 0.14.0 release notes, particularly the "How to deal with this change" section:
https://github.com/hyperledger/composer/releases/tag/v0.14.0
You need to update your ACLs and redeploy your network, binding a network admin participant.
There are two ways for specifying the business network administrators
on the command line: Note: This option is the one most users will
want! When running composer network deploy and composer network start,
in addition to the normal parameters you would use, you should also
include -A admin -S to bind the admin identity as a network admin
participant. If you don't do this, the identity you use to deploy the
business network, usually PeerAdmin, will be bound into the business
network as a business network administrator, and this is probably not
what you want.
I am getting following error while running composer rest server. I am using aws ubuntu 16.04 server.

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
I have v0.8.0 of hyperledger composer installed and when I try to deploy the business network using the following command I get an install chaincode error
composer network deploy -a test.bna -p hlfv1 -i admin -s adminpw
And the response is
Error: error trying to deploy. Error: error trying install chaincode. Error
What is the problem ?
The security model changed after hyperledger v1.0.0-alpha1. Now peers have the concept of Admin users. The userid 'admin' is a userid controlled and owned by the certificate authority server that is provided as part of the fabric composer development hyperledger fabric and has no authority on the Peer.
The Development fabric pre-loads the peer's Admin id into the KeyValStore defined by the profile 'hlfv1' and calls it PeerAdmin. This is the userid you must specify in order to deploy a business network onto the peer.
As this user has already preloaded it doesn't have a secret but hyperledger composer currently requires a secret to be specified. It doesn't matter what you specify for the secret so long as you specify something. So the deploy command looks like
composer network deploy -a test.bna -p hlfv1 -i PeerAdmin -s anything
