我有一个webRTC项目，可以在本地计算机上工作（nodeJS + firefox / chrome）。当我尝试将其部署到Amazon云下时，firefug出现问题：“ Ice Connection Failed”（在chrome上工作正常）
这是从服务器收到的SDP：

当我在本地测试时，我有这个额外的标签：
a=fmtp:126 profile-level-id=42e01f;level-asymmetry-allowed=1;packetization-mode=1
也许是一个问题，因为该标签不存在？
更新：
我曾尝试使用Google /其他眩晕/转弯，但行为并未改变 这是chrome和firefox coturn的日志
