Bigbluebutton webrtc issue

[jayalakshmi j]

 Hi

We have setup bigbluebutton on AWS t2.large server with his document http://docs.bigbluebutton.org/2.0/20install.html .

Our BigblueButton server is working fine but we are getting a webrtc error message

WebRTC Audio Failure: Error 1010: ICE negotiation timeout

With the bbb-conf check we are getting this output

[Fred Dixon]

Hi,

Can you verify that the ports are open on the server, see

  http://docs.bigbluebutton.org/install/install.html#configuring-your-firewall

Regards,... Fred

Hi Fred

Thanks for the response, we were out of town for few weeks that is the reason for the delayed response.

We had check that all the port is opened in aws security group, please see the attached image down.

Have you tried the Dummy NIC?

[jayalakshmi j]

Hi Matt

Our Webrtc error code is 1010, on the dummy nic card documentation its showing there 1002. That is the reason we didn't check with that one

If your firewall doesn't support a UTurn NAT you might try the dummy NIC... If you're using AWS access groups can you also ensure you're not filtering UDP outbound? The firewall ports are really inbound allowances only, and FreeSwitch responds with UDP ports well outside of the documented range...

Hi Matt

Thanks for the response. Our outbond rule is allowing by default to all protocols and to all ports to any where, please see the attach image down.

I had tried with dummy nic by adding additional internace with this command

sudo ip addr add
EXTERNAL\_IP\_ADDRESS/32 dev lo

and added external ip address in this file /opt/freeswitch/conf/sip_profiles/external.xml

Now am getting 1002 error

Please see the attach images below

You have to replace the external IP with the address of your server.

[jayalakshmi j]

Hi Matt

I had replaced when i try with the dummy nic card

I've had a ton of issues with WebRTC. It was typically because I had missed a step, fat fingered a config, or otherwise... When you connect thru chrome or Firefox, after it fails do an about:WebRTC in Firefox or chrome://webrtc-internals and look for the remote session info (Firefox refers to it as remote sdp). I was getting an internal IP for that... Will never work and throw a 1002. Ended up being commented out lines in the XML... Don't ask me why. I'm going to setup bigbluebutton from scratch on a t2.micro just to do it as we haven't deployed this in AWS before...

OK, thanks jayalakshmi... know that when I say 'we' I mean 'me'... The developers are awesome but I'm just a simple user... probably not a today or this week thing... just something I want to play with.  Can you test connect and get the remote SDP output?  You might find where your problem lies.

1002 typically means that there's either no inbound firewall rules in place or you can't hairpin NAT.  Have you tried the curl test?

Thanks... I'd go back thru the configuration docs and ensure you have everything set properly in vars, external, and the bigbluebutton-sip.properties.  It sounds like the server isn't listening on 7443.

Hi Matt

This is the debug result generated with chrome browser. With firefox i am not getting any error with the generated webrtc file

If you're not getting anything from firefox, that probably means you can't make a connection with WebRTC, hence the 1002 error.  Do you have the necessary ports allowed inbound?

• TCP ports 80, 443, 1935, and 7443
• UDP ports in the range 16384 - 32768

The 1002 error is shown when the initial websocket fails to connect. The websocket is the signalling layer and is actually set up before anything specific to WebRTC actually starts.

The part that changes drastically with the dummy NIC steps is that nginx starts redirecting the websocket connection from a local address to the external address. Basically nginx receives a request to /ws on your server and tries to forward it to EXTERNAL_ADDRESS:7443. The things to check are that IP address for the "wss-binding" in /opt/freeswitch/conf/sip_profiles/external.xml is the same as what your dummy NIC is set to and that it's the same as what nginx is set to. The other thing to check is that the computer that you have BBB installed on can connect to EXTERNAL_ADDRESS:7443. I think the nignx logs might have more info about the failed redirect also.

Hi Chad and Matt

The ip address pointed to this file /opt/freeswitch/conf/sip_profiles/external.xml

is external ip. That same ip only we pointed in dummy nic card.

Which nginx file did you means this conf file /etc/bigbluebutton/nginx/sip.nginx

For this configuration file there we pointed internal ip. But if a change to external ip am getting 1010 webrtc error

For the nginx configuration file /etc/ngnix/sites-avalible/bigbluebutton

We are pointed domain name

*This point is not clarified for me

The other thing to check is that the computer that you have BBB installed on can connect to EXTERNAL_ADDRESS:7443

The nginx log we are getting this error, please see the attached images bellow

Jayalakshmi J

1010 is closer to the finish line. You need the external and the 7443 in that config. From there, connect again to get the 1010 do an about:WebRTC in Firefox to make sure you're giving out the external IP. It was outbound filtering on one and not having the external IP in the externals file in the other.

Your nginx log shows a different IP...

Hi Matt and Jayalakshmi,

To make it easier to setup BigBlueButton 2.0-beta on Amazon EC2, we've created an install script called bbb-install.sh that now automates many of the installation steps (including the creation of an SSL certificate from Let's Encrypt).  See

  https://github.com/bigbluebutton/bbb-install

To show how bbb-install.sh works, we put together a video showing how to install BigBlueButton on a t2.large:

    https://youtu.be/-Xdy57rsbow

 Here's a screen shot of BigBlueButton installed using bbb-install.sh now running on a t2.large at https://t2large-test.bigbluebutton.org/.  

Note: A t2.large is a bit under-powered for BigBlueButton as it only has 2 CPU cores (the docs recommend at least 4 cores).  We would recommend installing on a c5.xlarge compute intensive CPU type which as 4 course and is very efficient.  Regardless if you choose a t2.large or c5.xlarge, the steps in the above video are the same.

We encourage you to try using bbb-install.sh to setup BigBlueButton 2.0-beta on a EC2 instance and let us know how it works. 

Regards,... Fred
