Chromecast 强制转换连接超时

我有一个定制的接收器应用程序（html页面+js和css），它只包含一个用于测试的iframe。我将接收器应用程序本地加载到与ChromeCast相同的Wi-Fi网络上。问题是，它连接良好，然后加载iframe，一切都很好，但在21秒的固定时间（每次）后，我得到一个错误代码15超时。我已经尝试在appConfig中将maxInactivity设置为6000，但没有效果。有什么想法可能是错的吗

值得一提的是，我也尝试将receiver应用程序放在一个域上，但没有任何区别

编辑：根据请求添加一些接收方日志。请注意，调试器可能有一半的时间甚至不显示日志，但不管怎样。。。下面是调试器生成的所有日志，包括一些对当前问题不太有用的日志

稍后编辑：最后我可以更改调试标志。这样可以得到更多的日志。检查下面

编辑：Android sender应用程序的唯一日志：

您必须显示吗？使用日志更新。没有注意到任何不寻常的事情。但我可能错了。当关闭时，你的发件人应用程序是否仍然连接并响应？是的，它仍然连接。你所说的响应是什么意思？它没有挂起。您是否尝试解决日志中出现的错误和警告？
