Hyperledger Fabric Error - Attempted to contact 2 Peers. Last error was Error: Failed to connect before the deadline

Question

我使用 byfn.sh 培养了 4 个同伴。
一切正常，我可以在 docker 个容器中看到 orderer、peers、CA nodes 等运行
然后我使用自定义服务层应用程序，该应用程序使用 Fabric Node SDK 连接到该网络。
我使用 byfn.sh 生成的 TLS CA 证书 (/usr/local/src/test_env/hlf_scripts/first-network/crypto-config/peerOrganizations/org1.example.com/tlsca/tlsca.org1.example.com-cert.pem)
以下是 docker 次调用的日志消息 Gateway.getNetwork(“mychannel”):

2020-01-14 22:12:20.981 UTC [comm.grpc.server] 1 -> INFO 083 unary call completed grpc.service=discovery.Discovery grpc.method=Discover grpc.peer_address=192.168.80.1:38858 grpc.code=OK grpc.call_duration=515.21µs

2020-01-14 22:12:21.012 UTC [comm.grpc.server] 1 -> INFO 084 unary call completed grpc.service=discovery.Discovery grpc.method=Discover grpc.peer_address=192.168.80.1:38858 grpc.code=OK grpc.call_duration=552.801µs

然后我启动另一个客户端应用程序，它使用几乎相同的代码来操纵网络。这里的第一步是确保用户（在本例中为管理员）的身份存在并且可以导入到钱包中。同一段代码用于生成此标识，并使用相同的连接配置文件 (connection_org1.json)。可以创建身份并将其导入文件系统钱包。
我可以使用 Gateway.connect(…) 方法和连接配置文件 connection_org1.json 连接到网络。然而，在我调用 Gateway.getNetwork(“mychannel”) 的那一刻，我的问题就开始了。这是 Fabric SDK 返回的错误：

我尝试了使用不同证书的各种排列和组合，但没有取得任何进展。在线论坛表明这是订购者和同行之间的沟通问题。但是，orderer 中没有错误消息。

我在 chat.hyperledger.org 中问过这个问题，但还没有回复。

Answer 1

我太傻了。我的节点项目文件夹中有一个 crypto-config 目录（我不知道我什么时候可能已经复制了它......）并且它丢弃了 tlscacert 变量。

我已经删除了有问题的目录，现在它正在读取 .../first-network/crypto-config/.../<tlsca file>.pem

下的正确目录

有时（而且经常 :-) ）答案就在那里，但是太笨了看不到！！！
