我的webRTC项目有问题。我的代码在Chrome和Firefox直到版本52之前都可以正常运行。自Firefox 53以来，我收到以下错误消息:“ICE失败，请参阅about:webrtc了解更多详细信息”。这是我的代码:

我的turnserver配置如下所示:

# Note: actually, TLS & DTLS sessions can connect to the
# "plain" TCP & UDP port(s), too - if allowed by configuration.
#
listening-port=3478
# TURN listener port for TLS (Default: 5349).
# Note: actually, "plain" TCP & UDP sessions can connect to the TLS & DTLS
# port(s), too - if allowed by configuration. The TURN server
# "automatically" recognizes the type of traffic. Actually, two listening
# endpoints (the "plain" one and the "tls" one) are equivalent in terms of
# functionality; but we keep both endpoints to satisfy the RFC 5766 specs.
# For secure TCP connections, we currently support SSL version 3 and
# TLS version 1.0, 1.1 and 1.2. SSL2 "encapculation mode" is also supported.
# For secure UDP connections, we support DTLS version 1.
#
tls-listening-port=5349
# Listener IP address of relay server. Multiple listeners can be specified.
# If no IP(s) specified in the config file or in the command line options,
# then all IPv4 and IPv6 system IPs will be used for listening.

# Relay address (the local IP address that will be used to relay the
# packets to the peer).
# Multiple relay addresses may be used.
# The same IP(s) can be used as both listening IP(s) and relay IP(s).
#
# If no relay IP(s) specified, then the turnserver will apply the default
# policy: it will decide itself which relay addresses to be used, and it
# will always be using the client socket IP address as the relay IP address
# of the TURN session (if the requested relay address family is the same
# as the family of the client socket).

最佳答案
查看您的在线演示，远程SDP中没有候选人行，这表明该候选人从未添加。
sendMessage(choosenONE, 'candidate', event.candidate.candidate);
这将丢弃需要通过信号发送到远程对等方的sdpMid和sdpMLineIndex。将.catch添加到您的addIceCandidate以记录任何错误。
