Microsoft Bot框架 - 如何设置连接端口

您好！ 

我在使用Bot框架监听Linux服务器时遇到了一些问题。它似乎在建立连接时需要一个端口，但如果重新启动应用程序则不一样。更确切地说，我得到的例外情况如下：

I am having some issues using the Bot framework listening on a Linux server. It seems that it requires a port when the connection is established, but is not the same if the application is restarted. More precisely, the exception I get is as follow:

引起：java.net.ConnectException：无法连接到localhost / 0：0：0：0：0：0：0 ：1：61718

       在okhttp3.internal.connection.RealConnection.connectSocket（RealConnection.java:189）

Caused by: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:61718
        at okhttp3.internal.connection.RealConnection.connectSocket(RealConnection.java:189)

或

或

引起：java.net.ConnectException：无法连接到localhost / 0：0：0：0：0：0：0：1：61718

       在okhttp3.internal.connection.RealConnection.connectSocket（RealConnection.java:189）

Caused by: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:61718
        at okhttp3.internal.connection.RealConnection.connectSocket(RealConnection.java:189)

等等。

打开一个端口不会有问题，只是总是相同 - 最好是可配置的。在本地测试机器人时，在Windows开发环境下，不会发生错误，一切正常。只有它发生在生产服务器上，
主要基于Linux。

It would not be a problem to open a port, just to always be the same - preferably configurable. When the bot is tested locally, under a Windows development environment, the error does not occur, all is working fine. Only it happens in production servers, mainly Linux based.

有没有办法解决这个问题？

Is there any way to fix this?

谢谢。
