jpos 网关：无法将从远程主机收到的响应消息发送回请求的客户端
jpos Gateway : Not able to send back the response message received from the remote host to the client requested
我是jpos的新手。尝试开箱即用 jpos-2_1_3。我可以看到转发到远程主机的消息和返回的响应，但是响应消息没有传送到请求的client.Getting下面的错误
[HOST_UNREACHABLE] o.j.t.p.QueryHost.expired:111 'mux.rsc' 不响应
我查看了客户端状态，连接中，等待响应
我的配置文件如下

如果我能提前得到一些帮助来解决这个问题就更好了issue.thanks。
总结一下评论中解释的答案，问题是字段 11 与响应不匹配。因此，多路复用器不知道传入消息是对请求的响应。
您可以查看用于匹配 QMUX 请求响应的默认字段，并在 jPOS programmers guide 第 8.3.2 节
中了解如何配置一组不同的键
