我正在使用带有 Debian 映像的 beaglebone-black armv7 作为 HLF nodejs 客户端应用程序。该应用程序使用fabric-client、fabric-ca-client、fabric-network节点模块，并构建为客户端调用的rest API（使用curl进行测试），然后该API作为通往HLF网络的网关，这要归功于连接配置文件配置。

问题是完全相同的应用程序（具有完全相同的连接配置文件）在我的 Ubuntu 机器上运行良好（它与部署在 AWS 实例中的网络通信）但是，当使用 Debian 在 armv7 上工作时，客户端即使它设法成功注册（来自 CA 容器的 docker 日志确认）在调用或查询链码时无法与对等方通信"Error: Failed to connect before the deadline".

我不明白为什么我会收到此错误，这可能取决于我的 Ubuntu 机器和我的嵌入式 Debian 设备之间的差异，或者也由于我不知道的设置或配置。

显然，Debian 的节点模块已正确编译，因为我从 package.json 开始在 Debian 设备本身上使用了 npm install。

在我收到的错误下方。

客户端：

curl http://localhost:3000/myBalance/ArmClient
