Question

我在使用Raft共识协议时遇到此错误，在该协议中，我设置了5个订购者（第1个服务器中有1个，其他2个服务器中有2个），即orderer1到orderer5。一切都可以通过设置正常进行，所有订购者都参与了订购者选举过程，但是当我尝试调用事务时，却遇到了这样的错误：

[ERROR] invoke-chaincode - Failed to order the transaction. Error code: SERVICE_UNAVAILABLE

仅当我尝试使用orderer2调用但与其他任何orderer一起使用时，才会出现此错误。请帮助解决问题。

这是orderer2及其运行的日志：

Answer 1

我也遇到了这个问题，orderer2也是如此。事实证明，我在订购者配置中输入了错字。在General.Cluster部分中，我不小心将ClientCertificate和ClientPrivateKey字段重命名为ServerCertificate和ServerPrivateKey。我切换了它们，将Server *值留为空白，并与其他证书指向我的客户端证书，一切正常。

无法订购交易。错误代码：SERVICE_UNAVAILABLE（使用筏式共识协议）
