自己STUN, 依然无法正常在外网显示视频流

[BearCooike]

简单说一下现在的情况:

1. 在内网下, 和数字人服务器一个网段, 走外网链接能正常connected,并显示视频流, 切到外网, 前后端一切正常, 但一直connecting.
2. 内网没有防火墙, 所以不存在udp的问题,
3. 外网服务器上用coturn搭了一个STUN, 当外网调用offer接口时, coturn日志如下:

外网服务器的内网IP: IP-A   外网服务器的外网IP: IP-B  客户端IP: IP-C

为了测试方便, 目前内网服务器和外网服务器的提供给livetalking和coturn的udp端口均被限制在20000-20020.

现在问题就是一直connecting.

前后端代码里面turn和stun都配置了吗
