Description

@JamesbNG

Hi, If a TURN server responds with Allocate error response (error 300: Try Alternate) then webrtc will fail to get a relay ip causing relay only mode to break and fallback connection.

ice WARNING: 2026/01/02 06:11:40 failed to allocate on TURN client relay.communication.microsoft.com:3478 Allocate error response (error 300: Try Alternate)
