peerConnection connectionState failed on AT&T wireless

[johnkcox]

We have an odd situation where we cannot create a peer connection when one of the peers is on AT&T wireless (cell), but it works on wifi and on all other wireless carriers we've tested. We've tried a number of things to see if we could resolve it, including custom STUN/TURN ICE servers, but to no avail.

Has anyone else encountered this problem and have any suggestions as to how we can make this work? We've not been able to track down much information other than looking at the peerjs log messages. Is there something specific in there that can provide a clue as to where this is breaking down?

我们遇到了一种奇怪的情况，当其中一个对等点使用 AT&T 无线（蜂窝）时，我们无法创建对等连接，但它在 wifi 和我们测试过的所有其他无线运营商上都可以工作。我们尝试了很多方法，看看能否解决这个问题，包括自定义 STUN/TURN ICE 服务器，但都无济于事。

有没有其他人遇到过这个问题，对如何解决这个问题有什么建议？除了查看 peerjs 日志消息外，我们无法找到太多信息。其中是否有具体内容可以提供线索，说明问题出在哪里？

hi，Is there any solution later
