Android客户端与Node.js Gemini服务器WebRTC PeerConnection ICE交换后偶发失败

我正在开发一款开源Android助手应用，采用Node.js服务器作为Google Gemini API的桥接层，通过WebRTC实现Android客户端与服务器间的实时音频流传输。目前遇到的问题是：Android应用与Node.js服务器间的WebRTC连接有时会在ICE候选交换后失败，PeerConnection状态变为failed，音频流随即停止。

服务器关键日志如下：

Received message from client app: WEBRTC_OFFER
 Received WEBRTC_OFFER
 Added RTCAudioSource track to PeerConnection for outgoing audio.
Received message from client app: WEBRTC_ICE_CANDIDATE
Track event received. Track Kind: audio, ID: ..., Label: undefined
 Audio track received. Properties: id=..., kind=audio, readyState=live, muted=false
 RTCAudioSink created for track ID: ...
Added ICE candidate
WebRTC PeerConnection state changed: new
 Sent WEBRTC_ANSWER
 (multiple ICE candidates exchanged and added)
Sending 3200 bytes of PCM data (approx. 100ms) to Gemini.
WebRTC PeerConnection state changed: failed
WebRTC PeerConnection failed.
WebRTC connection closed/failed/disconnected. Stopping audio sink if it exists.
RTCAudioSink stopped due to connection state change.

我已尝试添加重连机制，但问题仍未解决。若有人能解决此问题，我将万分感激。
