Environment

• LiveKit SDK Version: 2.14.0
• Platform: Android
• Issue: Connection fails when forcing ICE transport type to RELAY

Description

I'm trying to force RELAY transport for calls using the configuration below, but it fails to establish connections

room.connect(  
    livekitWss,  
    livekitToken,  
    ConnectOptions(  
        rtcConfig = PeerConnection.RTCConfiguration(emptyList()).apply {  
            iceTransportsType = PeerConnection.IceTransportsType.RELAY  
            sdpSemantics = PeerConnection.SdpSemantics.UNIFIED_PLAN  
            continualGatheringPolicy =  
                PeerConnection.ContinualGatheringPolicy.GATHER_CONTINUALLY  
        }  
    )  
)

Additional Information

• iOS works fine with the same server configuration
• The issue only occurs when forcing RELAY transport
• Connection works on Android when not specifying the transport type (allowing all transport types)

Is there additional configuration required for Android to work with RELAY-only connections?

Please let me know if you need any additional information. Thank you in advance for your help!
