Please help me!
Hi, I'am test accessing the stream with the VLC Player
but it's not connect, and show "WritePacket WebRTC Client Offline"
it's Prompt in google chrome browser
your chrome client not send ack or offline.maybe you should check connection.
According to the log, your browser is not connected during peerconnection. Maybe your browser can't directly access the server. HTTP requests are forwarded through a gateway, right?
Hi, @vdalex25 and @danbao12138 Thanks for your reply.
there any messages in the chrome console
How to solve the problem, thank you
Hi, @vdalex25 Thanks for your reply.
access to the stream
http://203.145.221.148:8889/
the rtsp link is rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov (config.json)
I decode the SDP information transmitted from your server as follows：

Your server is deployed in a LAN with IP 192.168.211.3, and your HTTP requests is forwarded through 203.145.221.148 server. Your browser is not connected during peerconnection, because your ice-candidate is wrong.
a=candidate:384879717 2 udp 1694498815 203.145.221.148 49825 typ srflx raddr 0.0.0.0 rport 49825
Your question is the same as #73
In fact, if the author can solve issue #77 or #73, he can also solve this problem.
I also have a solution. You need to change some code. You can modify its SDP information, change 192.168.211.3 to 203.145.221.148 , and then map the port used by peerconnection to the host.
