Ngrok我无法访问我的服务

Question

我使用Apache tomcat和第2轴（我正在使用ubuntu）使用Java进行Web服务这个Web服务调用了一些程序并且在localhost中运行得很好（我通过运行也使用Java构建的Web服务客户端来检查它）。现在我想用Ngrok发布它。 这是我使用的代码：

ngrok http 8080

我从de ngrok获取链接，我可以从任何地方访问我的网络服务wsdl

如果我从其他PC访问URL，我会在Ngrok屏幕上看到一些动作 然后我将Web引用添加到我的Xamarin APP并且它加载没有问题即使我可以看到我的Web服务的所有方法。显然一切都运行正常，但是当我运行我的应用程序时，服务器没有响应，并且ngrok屏幕也没有移动（我100％即时调用Web服务）。我很确定，因为我使用完全相同的代码调用其他服务。

发生了什么事？
