WebRTC stream not publishing in Firefox

[manikandan]

Hi,

WebRTC Stream publishing in firefox getting failed whereas it works in Chrome. When I checked with server logs, the stream failed due to "ICE timeout"
Please check the log messages below:

Good day.
Please collect a report as described here including traffic dump on server side, then send it to support@flashphoner.com, we will check.
Please also note that old Firefox builds (before 68) do not support DTLS 1.2 correctly, so DTLS User Agent setup may be required.

Thanks Max. Sent the mail with report logs.
Is this issue related to any websocket SSL with firefox? If it is so, "createSession" method should also fail. right?
But I can able to establish connection and stream publish is only not working.

No, this is not related to websocket connection.
We checked logs. It seems like you're trying to publish from local network. In this case, please add the following parameter to flashphoner.properties file

rtc_ice_add_local_interface=true

If this does not help, please collect a report again including traffic dump

Max, you are awesome. Stream works in Firefox now.
May I know why that issue happened in Firefox but not in other browsers?

When WebRTC connection is establishing, on ICE stage, a server sends to client SDP with addresses and media ports to connect (candidates). By default, only external IP is added to SDP candidates list. Firefox probably is more strictly than Chrome, and requires to add local IP to candidates too.

Thanks for the update Max.
