Javascript iceConnectionState已断开连接（通过internet使用时）

这个问题以前有人问过，但我还没有找到答案。我的问题基本上和前面描述的一样

我正在尝试使用PeerJS建立webRTC连接。它在局域网中工作完美无瑕，但我无法让它在互联网上工作。我使用coturn作为TURN服务器，但到目前为止还没有解决问题。Chromium控制台打印出以下内容：

我使用的对等对象如下所示：

var peer = new Peer(
    GetURLParameter('id'),
    { key: peerKey, debug: peerDebug},
    {config:
        { 'iceServers': [
            { url: 'stun:[server ip here]:3478'},
            { url: 'turn:[server ip here]:3478'}
        ]}
    }
);

Chain OUTPUT (policy ACCEPT)

ACCEPT     udp  --  anywhere             anywhere             udp dpt:3478

var peer = new Peer(
    GetURLParameter('id'), {
        key: peerKey,
        debug: peerDebug,
        config: {
            'iceServers': [
                { url: 'stun:[server ip]:3478'},
                { url: 'turn:[server ip]:3478'}
            ]
        }
    }
);

使用turnserver-L[服务器ip]启动turnserver时，coturn会打印以下内容：

PeerJS:  Added ICE candidate for: client1

0: IO method (auth thread): epoll (with changelist)

最后，由于我猜这可能是一个安全问题，我的iptables配置目前看起来如下：

var peer = new Peer(
    GetURLParameter('id'),
    { key: peerKey, debug: peerDebug},
    {config:
        { 'iceServers': [
            { url: 'stun:[server ip here]:3478'},
            { url: 'turn:[server ip here]:3478'}
        ]}
    }
);

Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:3478
ACCEPT     udp  --  anywhere             anywhere             udp dpt:3478

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:3478
ACCEPT     udp  --  anywhere             anywhere             udp dpt:3478

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:3478
ACCEPT     udp  --  anywhere             anywhere             udp dpt:3478

var peer = new Peer(
    GetURLParameter('id'), {
        key: peerKey,
        debug: peerDebug,
        config: {
            'iceServers': [
                { url: 'stun:[server ip]:3478'},
                { url: 'turn:[server ip]:3478'}
            ]
        }
    }
);

有人知道如何让这东西工作吗？任何帮助都将不胜感激

编辑：原来我的回合配置JSON很混乱。我的新对等对象现在看起来如下所示：

var peer = new Peer(
    GetURLParameter('id'),
    { key: peerKey, debug: peerDebug},
    {config:
        { 'iceServers': [
            { url: 'stun:[server ip here]:3478'},
            { url: 'turn:[server ip here]:3478'}
        ]}
    }
);

Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:3478
ACCEPT     udp  --  anywhere             anywhere             udp dpt:3478

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:3478
ACCEPT     udp  --  anywhere             anywhere             udp dpt:3478

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:3478
ACCEPT     udp  --  anywhere             anywhere             udp dpt:3478

var peer = new Peer(
    GetURLParameter('id'), {
        key: peerKey,
        debug: peerDebug,
        config: {
            'iceServers': [
                { url: 'stun:[server ip]:3478'},
                { url: 'turn:[server ip]:3478'}
            ]
        }
    }
);

这给了我更多关于TURN server的反馈（因此我想我的方向是正确的），但问题仍然存在

EDIT2: 嗯，这很奇怪。这似乎是某种跨浏览器兼容性问题。使用mido建议的TURN服务器测试工具，我在Firefox中得到的结果与在Chromium中得到的结果不同。我打算使用Chromium，因为它的kiosk模式对我的应用非常方便。但是回到回合服务器。在Firefox中，当使用用户帐户时，一切似乎都很正常： github测试页面的输出：

0.004   1   host    0   UDP 192.168.178.28  39919   126 | 32512 | 255
0.005   2   host    0   UDP 192.168.178.28  56123   126 | 32512 | 254
0.076   1   srflx   1   UDP 178.39.74.108   39919   100 | 32543 | 255
0.077   1   relay   2   UDP [Server IP ]    52147   5 | 32543 | 255
0.098   2   srflx   1   UDP 178.39.74.108   56123   100 | 32543 | 254
0.099   2   relay   2   UDP [Server IP ]    60002   5 | 32543 | 254
0.099   Done

但是，允许匿名访问TURN服务器并尝试在没有用户名和密码的情况下登录，绝对不会发生任何事情

Chromium中的不同故事：提供用户名和密码后，会发生以下情况：

0.002   1   host    138421141   udp 192.168.178.28  42343   126 | 30 | 255
0.002   2   host    138421141   udp 192.168.178.28  49001   126 | 30 | 254
0.028   1   srflx   842163049   udp 178.39.74.108   42343   100 | 30 | 255
0.049   2   srflx   842163049   udp 178.39.74.108   49001   100 | 30 | 254

…当TURN server上的终端反复打印401条错误消息时。在我看来，使用chromium时，凭据永远不会到达服务器。401错误消息表示用户名为空

我真的可以用铬做那东西。有人知道如何让它工作吗？

请检查你的回合服务器的防火墙设置。

对于初学者，你的回合服务器在哪里托管，它有公共ip吗？我正在使用一个基于Ubuntu的虚拟服务器（他们称之为“droplet”）。我可以从这里ping它，所以我猜，是的，它有一个公共ip。你能测试回合是否独立工作，检查这个，通常对于回合，人们提供用户名密码，他们在你的回合中丢失了配置你交换网络了吗？Peerjs在你交换网络时工作不好。谢谢链接，mido。我将运行一些测试并报告结果。似乎是个有用的工具@你说的交换网络是什么意思（老实说，我不太擅长我所做的…）？我正在建立一个连接，从我家的DSL连接到4G/LTS连接上的raspberry pi。谢谢你迄今为止的帮助！测试时，我通过调用ufw disable禁用了服务器上的防火墙。我想这应该是防火墙的问题了。但谢谢你的提示。即使防火墙被禁用，也一样。
