node.js - WebRTC 视频适用于其他托管网站，但不适用于 Heroku

问题描述

再会！

我有一个带有 Socket.io 的 WebRTC 应用程序来发送信号。我有一个通过测试的 STUN/TURN 配置https://test.webrtc.org/

到目前为止，我的应用程序的 WebRTC 部分已经过（多次）测试：

确切的错误信息是：

'ICE 失败，你的 TURN 服务器似乎坏了'

在其他平台上，它可以工作，不需要 TURN 服务器，但在 Heroku 上却不行，它完全失败了。

为什么是这样？Heroku 是否在做一些干扰 WebRTC 连接初始化的事情？Socket.io 工作正常，服务器上没有错误，所以问题很可能是建立对等连接。

更新：

这是来自失败的 WebRTC 连接的日志。如您所见，它有一个报价，一个答案，还有冰候选人，但我不知道为什么仍然出现错误'ICE连接失败'
