Hyperledger fabric 在对等方上调用事务时发生连接错误

我正在尝试执行我用couchdb和java编写的链式代码。我使用第一个网络示例创建网络并实例化代码。网络已创建，链码已顺利安装。然后我进入容器并执行事务。起初它工作正常，但突然它开始给我这个错误，现在我找不到解决办法。我不知道它是否与couchdb连接有关

Error: error getting endorser client for invoke: endorser client failed to
connect to peer0.org2.example.com:7051: failed to create new connection:
connection error: desc = "transport: error while dialing: dial tcp
172.24.0.9:7051: connect: connection refused"

下一个是我用来开链码的密码

peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C $CHANNEL_NAME -n mycc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["createCustomer","c1","tom"]}'

很多人问过链码是否安装在对等机上，我可以确认。这意味着您的端口没有为对等机打开，请检查snippet ports部分，您的对等机docker文件应该是这样的

peer0.org1.example.com:
    container_name: peer0.org1.example.com
    image: hyperledger/fabric-peer
    environment:

您是否在peer0.org2.example.com上安装了该链码？请尝试：telnet peer0.org2.example.com 7051如果无法到达该对等端口，则您需要处理网络或节点中的某些内容。这可能是由于以下错误导致的-1或者链码未在两个对等端口上安装，或者2您的对等端口无法访问。要检查对等机是否可访问，只需尝试访问firefox上的ip地址：对等机端口，如果您得到的响应意味着对等机可访问，其他事情您可以检查该对等机上是否安装了链码？@BrajeshKumar我尝试通过firefox访问，就像您对对等机说的，但它似乎不起作用，所以正如你所说的，似乎无法访问同龄人。你知道这里的问题或解决方案是什么吗？谢谢你帮我解决ir问题，我的端口出现了一个错误。
