WebRTC conncet with SFU server failed using Lite ICE

I’m trying to connect my web client with my SFU server. And the SFU server implements lite ICE.
Here’s the SDP sent by my web client:

The pcap file captured by WireShark shows that SFU server send a BINDING SUCCESS response.

But the connectionState and iceConnectionState of my RTCPeerConnection is always “failed”.

I have checked the remoteDescription.sdp of my RTCPeerConnection object.
The line a=ice-lite disappeared.

What’s the problem? Is the SDP generated by my SFU server wrong?
