webrtc ice_server从未注册为候选冰

Question

I am building a webrtc client where i am using a turn and stun server. This is working if i am turning of the firewall. When i breakpoint the on ice candidate function i see that my ice servers are not added as ICE candidate.

This is the code:

var rtc_configuration =
    {
        iceServers: [
            {urls: "stun:numb.viagenie.ca"},
            {urls: "turn:numb.viagenie.ca", username: "username", credential: "credential", credentialType: "password"}
        ],
        bundlePolicy: "balanced",
        iceTransportPolicy: "all",
        rtcpMuxPolicy: "negotiate",
        iceCandidatePoolSize: 20,
        certificates: []
    };
    var peer_connection = new rtc_peer_connection(rtc_configuration);
    peer_connection.onicecandidate = pc_on_ice_candidate;

but when i breakpoint on the onicecandidate funtion, only the default candidates are added, and not the ice servers that are in the configuration. I am using the last version of firefox.

Does anybody have a suggestion?

我认为问题是因为TURN服务器传输类型是UDP，并且由于防火墙的原因，UDP端口将被阻止，因此没有ICE候选者，请尝试使用TCP传输模式添加TURN凭据...
