that question but with logs! :slight_smile: Here’s my logs and stuff:

If ICE does not connect it may be due to network problems, lack of UDP or wrongly configured server, etc. If it works in Chrome (does it?) it may be because Chrome supports ICE over TCP and Firefox doesn’t).

But well, you did not provide that info.

Seems to work in chrome (or at least I don’t get an error).

I have UDP and TCP enabled. I even tried disabling TCP and only using UDP.

It’s running on localhost so there shouldn’t be any network issues.

I can provide any logs or more information needed including server config. What do you need?

Does “localhost” mean that mediasoup v3 is listening in 127.0.0.1 UDP?

Yes. 192.168.1.197 is the internal IP of the computer I am working on. So 192.168.1.197 and 127.0.0.1 (localhost) both point to the same machine,

Yes, it seems so according to the logs. No, browsers do not connect ICE to 127.0.0.1 UDP, but Chrome connects to 127.0.0.1 TCP, and there is TCP in your logs, so Chrome works.

Don’t make mediasoup listen in 127.0.0.1.

I am confused, why can’t I use 127.0.0.1 for ICE? If not, what should I set it to? My internal address, 192.168.1.197?

I changed to 192.168.1.197 (my internal address) for the following setting and it worked.

webRtcTransportOptions:
                {
                    listenIps:
                        [
                            {
                                ip: process.env.MEDIASOUP_LISTEN_IP || '192.168.1.197',
                                announcedIp: process.env.MEDIASOUP_ANNOUNCED_IP
                            }
                        ],

(In production I will set with environment variable).

Thanks!

Is there a reason that Firefox doens’t allow ice as 127.0.0.1?
