livekit connection error: could not establish pc connection

[Tylermeek]

hello,I have been tried to run this project for couple days.But I am stuck by this livekit Error.

It happened after I chose the way to enter the room. I tried to debug, in order to find out where the problem is.
I found out that the connect method threw out this error.

This url and token should be correct.
So I went to check the Livekit server. I tried for couple times, and found out that the connection closed after the perr connection tried to connect.
Here is part of the logs.

2024-01-06T11:15:23.930Z        DEBUG   livekit.transport       rtc/transport.go:643    peer connection state change    {"room": "room01", "roomID": "RM_6CdshrkrpaQC", "participant": "1704539345689", "pID": "PA_Xa6XWksuHksX", "remote": false, "transport": "SUBSCRIBER", "state": "connecting"}

I don't know why the connection closed.About the firewall,my firewall didn't block the ports that livekit server need,but I still got that error.
Here is my livekit.yaml and config.yaml
