Cryptography 错误：获取广播客户端时出错：rpc错误：代码=不可用描述=传输：写入tcp

我正在尝试使用命令使用自定义cryptomaterial（不在FabricsSample中工作）创建通道

 peer channel create -c myc -o orderer2.IdentityPreservationSystem.com:7050

得到这个错误

Error: Error getting broadcast client: rpc error: code = Unavailable desc = transport: write tcp 172.20.0.7:42446->172.20.0.3:7050: write: connection reset by peercontainers are running with the services of peers CA and orderers.

Usage:
  peer channel create [flags]

Flags:
  -c, --channelID string   In case of a newChain command, the channel ID to create.
  -f, --file string        Configuration transaction file generated by a tool such as configtxgen for submitting to orderer
  -t, --timeout int        Channel creation timeout (default 5)

Global Flags:
      --cafile string                       Path to file containing PEM-encoded trusted certificate(s) for the ordering endpoint
      --certfile string                     Path to file containing PEM-encoded X509 public key to use for mutual TLS communication with the orderer endpoint
      --clientauth                          Use mutual TLS when communicating with the orderer endpoint
      --keyfile string                      Path to file containing PEM-encoded private key to use for mutual TLS communication with the orderer endpoint
      --logging-level string                Default logging level and overrides, see core.yaml for full syntax
  -o, --orderer string                      Ordering service endpoint
      --ordererTLSHostnameOverride string   The hostname override to use when validating the TLS connection to the orderer.
      --tls                                 Use TLS when communicating with the orderer endpoint
  -v, --version                             Display current version of fabric peer server

“创建”命令中有错误。您需要为使用configtxgen命令生成的通道指定通道事务文件（.tx）

对等通道创建-c myc-f指定\u通道\u事务\u文件-o order2.IdentityPreservationSystem.com:7050

现在我收到此错误授权更新错误：验证读取集错误：现有配置不包含[Group]的元素/Channel/Application/OrgMSP，但在读取集中。我可以知道您是如何生成加密材料的吗？使用cryptogenOk，然后请按照下面提到的链接将组织添加到现有频道中。还要确保您使用的是正确的组织MSP和频道名称。按照上面的链接，让我知道为什么我应该添加另一个组织。我的业务逻辑需要一个组织
