amazon-ec2 - BigBlueButton:WebRTC 音频失败:错误 1010:ICE 协商超时

Question

我已经设置了一个 Ubuntu 16.04 EC2 t2.medium 服务器并按照此处的说明进行操作 http://docs.bigbluebutton.org/2.0/20install.html安装 BigBlueButton 2.0-beta。
当我登录演示 session 室并选择麦克风时，它显示正在调用...然后更改为正在连接...然后我收到一条消息:

WebRTC Audio Failure

Detected the following WebRTC issue: Error 1010: ICE negotiationtimeout. Do you want to try Flash instead?

这是控制台的输出:

请检查您的防火墙:

TCP 端口 80、443 和 1935 是可访问的。

如果您打算配置 SSL(推荐)，则可以访问 TCP 端口 7443，否则可以访问端口 5066。

可以访问 UDP 端口 16384 - 32768。

端口 80 未被其他应用程序使用。
