Does the demo use turn server?

General

I could pass stream via janus and coturn on my EC2 server but I have questions about the state of demo page of streaming.

Does it use turn server?

I run coturn because ICE shake hand fails without that on my environment.
However, if the demo runs without turn server, I want to run my own server without that.

No, our online demos don’t use a TURN server. It’s easy to add a TURN server to the demo pages you’ll deploy yourself, though (just check the commented code in the demos).

Thank you for replying.

I see.
Can I see configuration of janus online demo?
I want to refer that to run janus without TRUN server.

The following error occurs and cannot publish streaming by my janus on server that has public IP.
(I could run on local.)

[WARN] [5356358957979488] Error resolving mDNS address (5b2f5202-e61c-4558-8c75-f257d41ac29d.local): Error resolving “5b2f5202-e61c-4558-8c75-f257d41ac29d.local”: Name or service not known

The janus.cfg I tried.

nat: {
  nice_debug = true
  nat_1_1_mapping = "public ip of my server"
}

I have already done it.

though (just check the commented code in the demos).

Which information do you mention?
Can you show some url of that?

Thank you for the response but it seems client side.
I usedstreaming.js and streaming.html for testing.

What I want to see is janus.jcfg that used to run online demo.

I have already known this.

Does the online demo use this without any modification?

I could run my janus instance without turn server.
I miss took on configuration file so the setting was ignored.

janus.jcfg

nat: {
  nat_1_1_mapping = "11.22.33.44" # ip address of my server
}

janus runs even if the configuration file has trouble so I need check log carefully at waking up the instance.
