Question

使用appr.tc冰服务器（谷歌转服务器）时，我可以在任何情况下连接。但我无法连接我自己的转弯服务器。我通过coturn project配置了我自己的转弯服务器。

我正在使用谷歌的libjingle_peerconnection API创建一个Android Application来执行video call。

当我运行转服务器时：

我无法建立成功的连接对等体。问题在哪里？

当我使用appr.tc转弯服务器时，我可以打电话给每个同伴，所以我认为我的应用程序没问题。

Answer 1

将域名替换为137.74.35.124它应该可以工作，我希望Ur coturn服务器在公共IP上与137.74.35.124相同。

Answer 2

您正在使用WebRTC。 WebRTC中的中继候选者收获仅适用于凭证。您应该将以下配置添加到turnserver.config。

 listening-ip=137.74.35.124
 fingerprint
 lt-cred-mech
 user=guest:somepassword
 realm=saladem.com

使用turn:137.74.35.124:3478用户guest和密码somepassword。您可以在此处进行测试：https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/

如果测试显示接收候选者已被收获但是同伴中的连接仍然失败，则可能是您缺少配置文件中的外部内部ip映射。即你的转弯服务器在NAT后面。添加：

external-ip=[your-external-ip]/[your-internal-ip]

到turnserver.config。

有关如何在此处配置WebRTC使用的服务器的讨论：https://github.com/coturn/coturn/wiki/turnserver

Answer 3

就我而言，我收到了 CREATE_PERMISSION 403: Forbidden IP 错误，并且无法连接到网络外部的对等设备。这里的答案绝对帮助了我。我只为 external-ip 中的 turnserver.conf 设置了公共 IP。我将它设置为 / 并且它起作用了。类似于以下内容：

external-ip=13.some.thing.229/172.some.thing.else

为什么我的转弯服务器不起作用？
