WebRTC: Exchange SDP failed

[Kane9527]

SDP negotiation failed! The local SRS service uses SRS-Windows-x86_64-5.0-b3-setup and Docker has been tried, the configuration is rtc2rtmp.conf This is the case from Unity 19 to 22, com.unity.webrtc@3.0.0-pre.1~5 and 2.4 are also the same, I see the error is in this part of the code, Because there is an RTSP camera, it also pushes to the SRS service, but when pulling the stream, some computers also report this error, while some computers work well, which is very strange. 请问如何解决？是哪里出了问题？

你们有解决这个问题么，我推流也是这个问题，通过SRS的whip是正常能推的，到这边来就不能推了
