Hi Alex,

Can you try it with both FireFox and Chrome and let us know if you get the same error.

Also, confirm you have a working microphone with your computer.  

See the "Setting Up Audio" video for BigBlueButton on how to check that your microphone is connected and generating audio:

Are you on a laptop?  Is it possible for you to connect via a wireless hotspot (and thereby have a completely different network path) and try https://demo.bigbluebutton.org/ again?

Also, what version of the browsers are you testing?

Hi Alex,

Do you have a microphone on your desktop?  That would cause a 1004 on our server.

Having the same problem. I didn't have this problem with 1.0 but when I updated to 1.1 I started to get this problem with Chrome. Firefox works as usual.

I tried your demo (2.0) and I get the same error.

Hi Niels,

Chrome requires that the browser be connected to the server via SSL before it will allow the user to share their microphone.  FireFox is less restrictive.

When you try sharing microphone with https://demo.bigbluebutton.org/, does Chrome give you any warning next to the URL or does it show "Secure"?

What's the full error that you're getting? The 1004 code is generic and the actual cause will tell more.

Detected the following WebRTC issue: Error 1004: Failure on call (reason=Incompatible SDP). Do you want to try Flash instead?

Could you send me your full SDP from the browser console. I'm curious if anything stands out.

A getUserMedia failure should show up way before a the call tries to connect and you would get an 1004 "Incompatible SDP" error. That getUserMedia error looks like when you try to get a mic with Chrome on HTTP. Are you getting different errors on our demo server vs. your own server?

From home both demo (2.0) and our server (1.1) give an error message. From work only our server (1.1) gives an error message. A friend tested and got no error messages... Very strange...

Hi Mohellebi,

> but for the inside clients i got the 1010 error timeout...., any ideas for the causes?!! thanks!!!

See


The "inside clients" are behind a firewall.  The ICE communication has timed out, which might be a result of the firewall. Do you have any visibility to the Firewall logs (or a friend in IT if your within the company) that could help diagnose why ICE candidate negotiation is timing out?

You can test that the appropriate ports are accessible.  See

Can users on the inside access the public IP address or do you have a custom DNS entry for your inside users that resolves to a different internal IP so they can connect.

hy Chad, yes my users have their own DNS witch resolve the internal ip adress for my server. they haven't access to the public ip adress.

Hi,

> hy Chad, yes my users have their own DNS witch resolve the internal ip adress for my server. they haven't access to the public ip adress.

We recommend setting up the internal DNS so it resolves to the external IP address of the server.  This way, your BigBlueButton server can accept connections from a single incoming IP address.

Regards,... Fred

It's definitely the reason that the people inside can't use WebRTC. The FreeSWITCH setup that we use only returns one IP address for the browser to use to connect to and that IP address is going to be the public one. Your inside users are trying to connect to that and are getting stuck.
