coTURN 无法在 Mozilla Firefox 中进行握手

Question

我有一个使用 WebRTC 的 Web 和独立应用程序。我在 Amazon EC2 上有自己的 coturn 服务器。我根据 article 配置所有内容（也许这是一个错误？）。我用这个 stun/turn 服务器测试我的应用程序，一切都适用于 Chrome、Edge、Safari，但不适用于 Mozilla Firefox（已生成报价和答案）。我在控制台中收到以下错误：

ICE failed, your TURN server appears to be broken, see about:webrtc for more details

我假设我配置错误，所以这就是它不起作用的原因。我使用的 EC2 机器：

2 个私有 IP，
2x public IP（弹性 IP），
等级：T2.micro、
UDP/TCP 端口已打开。

coturn配置（/etc/turnserver.conf文件）：

listening-ip=0.0.0.0
external-ip={publicIP}:{privateIP}
external-port=3478
fingerprint
realm={publicIP}
lt-cred-mech
user={username}:{password}
log-file=/var/tmp/turn.log
verbose

Stun/Turn代码中的服务器配置：

RTCConfiguration.Create([|
      RTCIceServer.Create([|
          "stun:{publicIP}:3478"
          "turn:{publicIP}:3478"
        |], {userName}, {password}, RTCIceCredentialType.Password)
    |])

并且传输策略设置为 all。

而整个 turn.log 仅针对来自 Mozilla 的此请求：

任何提示我可能做错的地方都将不胜感激！

Answer 1

您应该仔细检查在 AWS 中为 EC2 实例定义的内部路由和一些关于入站流量的全局路由。如果 stun/turn 服务器在内部网络之外不可用，Mozilla Firefox 将是唯一无法执行 "handshake" 的服务器。 Chrome、EDGE、Safari 将在这种情况下工作并建立 P2P (srflx) 连接。

在我的情况下，所有 AWS 实例的入站流量都有一些额外的定义，这些实例阻止了到 stun/turn 服务器的流量。我意识到，当我尝试从一台计算机（连接到 VPN）到另一台（未连接到 VPN）测试 WebRTC 时，它在执行 "handshake".

时失败了

coTURN 无法在 Mozilla Firefox 中进行握手

coTURN unable to do a handshake in Mozilla Firefox

udp

mozilla

stun
