ios - 应用 RTC 调用无法从 ios 到 ios

Question

不能在 ios 到 ios 上工作 当我使用 appRTC server( https://apprtc.appspot.com) 进行测试时，调用正在从 iOS 到 iOS、从 iOS 到 Android、从 Android 到 iOS 工作。

但是我正在测试我的自定义服务器（http://192.168.0.100:8080）调用在 iOS 到 iOS 和 iOS 到 Android 上都不起作用。但是Android到iOS运行良好。

当我使用 appRTC 服务器和自定义服务器进行测试时，我发现以下日志。
