WebRTC视频可与其他托管网站一起使用，但不适用于Heroku

如何解决WebRTC视频可与其他托管网站一起使用，但不适用于Heroku

美好的一天！

我有一个带有Socket.io的WebRTC应用程序用于发信号。我有一个通过测试https://test.webrtc.org/

的STUN / TURN配置

到目前为止，我的应用程序的WebRTC部分已在以下位置进行了多次测试：

• 本地主机，同一台计算机，多个标签页：一切正常，视频和音频
• 局域网：一切正常，视频和音频
• Firebase，不同的公共IP地址：一切正常，视频和音频
• Heroku，不同的公共IP地址： ICE失败，或TURN错误

确切的错误消息是：

“ ICE失败，您的TURN服务器似乎已损坏”

在其他平台上，它可以工作，不需要TURN服务器，但是在完全失败的Heroku上就不能使用。

这是为什么？ Heroku是否在做一些干扰WebRTC连接初始化的事情？ Socket.io正常运行，并且服务器上没有错误，因此问题最有可能是建立对等连接。

更新：

这是来自WebRTC连接失败的日志。如您所见，它提供了一个报价，一个答案以及候选对象，但我不知道为什么仍然存在“ ICE连接失败”错误
