Expected behavior
尊敬的Mr.Tempotian
我遇到了设备与后端的WebRTC连接问题，请求得到您的帮助！
Actual behavior (suspected bug)
我采用的是MQTT信令，跟后端处于同一个局域网、公网、网段。
但日志却：在发送完sdpOffer并接收来自后端的answer并处理后，进行ICE协商交换握手，明明日志显示的已经完全按照流程在运行，但始终都无法连接，百思不得其解，只能向您请教！！
具体日志如下：（每次从状态”3“直接跳到状态”7“失败）

1、获取群组id，将id嵌入在sdp和ice的json字段中
2、发送sdpOffer
3、收到来自后端的answer和ice候选
4、丢给API处理answer，并完成ice交换
5、尝试连接到后端返回的内网地址
6、连接失败！❌
