I have follow Hyperledger Composer here and all step is done.
But when i restart my PC and try to connect to Hyperledger Composer via command 'composer-rest-server' have error like this:
enter image description here

Please help! Thank You.
See this answer for restarting the underlying Fabric before starting the REST Server.
When you restart your system, you also shut down all running docker containers. Restart containers(your blockchain network) before launching composer rest server.

Can someone please help me with this problem.
error [connectors/v2/FabricGateway] Failed to perform query transaction [ReadAsset] using arguments [2_4], with error: Error: error in simulation: failed to execute transaction 9ca49b08603ab086104fec8777546bbbc24d826a3900136b4a0e66aadf4bb6e4: could not launch chaincode basic_1:9820659c595e662a849033ca23b4424e87a126e8f40b5f81ace59820b81fe8e7: chaincode registration failed: error starting container: error starting container: API error (404): network _test not found
The report has been generated but all the transactions has failed.
It looks like the chaincode's Docker container failed to start for some reason. You will need to use the docker logs command to inspect the logs for the failure reason. Use the docker ps -a command to see what containers are available, including stopped / failed containers. Both the chaincode container (if it exists) and peer container logs may hold useful information.

Deploying a Hyperledger Composer blockchain business network to Hyperledger Fabric (multiple organizations) is working fine until i need to close my computer and try to connect again
I followed this tutorial=https://hyperledger.github.io/composer/v0.19/tutorials/deploy-to-fabric-multi-org
For the first time the command "composer-rest-server" worked fine but after there is an error and i am unable to connect again
That is the error:
To restart the REST server using the same options, issue the following command:
composer-rest-server -c alice#trade-network -n never -d n -w true

i got this error when i am trying to connect peers running in different machines .I found this error in docker logs of orderer.There is an error in docker logs of peer2 running in different machine
Failed obtaining connection: Could not connect to any of the endpoints: [orderer.example.com:7050]
You can find the orderer.yaml file at fabric-samples/config folder.
Going through the fields and their respective comments in orderer.yaml and core.yaml can help you to understand the method of configuring the network(orderer/peer).
And here you can get the info related to TLS.
When I ping blockchain business network using composer network ping command getting following error:

The answer and comments in this post should help you if you are using Composer v0.16.x
This tutorial should help with the format of the connection.json file.
If you are using v0.17.x, you will need this version of the tutorial.
UPDATE:
Composer v0.19 is now the latest version with many enhancements and some breaking changes. The tutorial has been updated accordingly and the revised tutorial is here.
