Error: Could not connect to the configured hostname/IP address

[implan...@gmail.com]

Hello Fred Sir!

When i configure BigBlueButton  to load session via http. All BigBlueButton functions works correctly.

But!

When i configure BigBlueButton to load session via HTTPS according to the instructions http://docs.bigbluebutton.org/install/install.html#configuring-ssl-on-your-bigbluebutton-server,

 I catch  Error: Could not connect to the configured hostname/IP address https://mysite

My website works correctly on https, and new meeting start correctly, but when i try to join on this meeting, i see this error in browser adress string

https://www.mysite.ru?errors=[{"message":"We could not find a config for this request.","key":"noConfigFound"}]

this is my nginx.conf

Here we see a proxy on 127.0.0.1:81

This is done because the BigBlueButton and my site are hosted on the same server.

81 port listen apache2. Here is port settings.

# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default.conf

Listen 81

#<IfModule ssl_module>
#       Listen 443
#</IfModule>

#<IfModule mod_gnutls.c>
#       Listen 443
#</IfModule>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

And this is Virtualhost settings apache2

<VirtualHost *:81>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        ServerName webinar.implant.ru

       
        DocumentRoot /var/www/bigbluebutton-default/basic/web
        SetEnvIf Scheme https HTTPS=on
     # SSLEngine on
      # SSLCertificateFile /etc/ssl/crt/implant.crt
      # SSLCertificateKeyFile /etc/ssl/privatewebinar/private.key

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,

        # It is also possible to configure the loglevel for particular

        #LogLevel info ssl:warn

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only

        #Include conf-available/serve-cgi-bin.conf

Hi Dmitriy,

Looking at this output

> # Error: Unable to reach default URL for presentation

> #

> #    http://10.12.10.66/default.pdf

> #

> # Check value for beans.presentationService.defaultUploadedPresentation in

> #   /var/lib/tomcat7/webapps/bigbluebutton/WEB-INF/classes/bigbluebutton.properties

It looks like bbb-web is not configured for https.  I would recommend trying to use bbb-install.sh to setup your server -- it can handle the creation of SSL certificate (through lets encrypt) and setting up the configuration using internal/external IP addresses.  See

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

Try the above and let us know if that gets you going.

Regards,... Fred

Hi Fred!

I did what you advised. The only difference is that I did the whole installation manually. And in manual configured nginx on, using the Let`s Encrypt certificate.

Bigbluebutton started working correctly on https =)

I think I made a mistake somewhere when installing BBB.

But now i have a new trouble.

I'm installing a new HTML5 interface.
On all computers BBB works correctly. The microphone, speakers and camera are connected to any computer, and users can enjoy all the functions of the BBB.
But when I connect to the BBB from an Android or OS X mobile phone, the mobile browser connects correctly to the BBB, but when the microphone or listening mode is selected. For example, I choose only listening.
The mobile browser first requests permission to connect to devices and when I give permission. It tries to connect, and then the message "Connection error" appears.

And so on all Android and OS X devices.

I tried to configure nginx with a valid certificate from the certification center.
The situation is exactly the same, everything works on the computers. On phones and tablets "Connection error"

Can you help me please.

Best regards, Dmitriy

I just tried to connect on your server and I think the problem is that your server is giving out a local IP for its candidate rather than your public IP. If you connect to audio through Firefox and then go to "about:webrtc" you should see the remote candidate being a different IP than your server's public IP. I think you should be able to follow these steps to fix your FreeSWITCH config http://docs.bigbluebutton.org/install/install.html#configuring-bigbluebutton-behind-a-firewall. If your server doesn't have a network interface with your public IP you will also need to do the "dummy NIC" steps so FreeSWITCH can bind to your public IP.

[implan...@gmail.com]

Hello, Chad.
You are absolutely right! When I set up my BBB for this instruction  http://docs.bigbluebutton.org/install/install.html#configuring-bigbluebutton-behind-a-firewall And I configured the Dummi NIC all functions started working correctly.
In our internal network, there is a problem when connecting to the "ru" zone from the internal network. I think that was the reason.

Now I have only one problem. When I try to connect a webcam from phones and tablets. I get the error message "Error connecting to webcooler"

What could be the reason?

And the second question. My colleagues and I decided to just take the server out of the internal network, to make a full-fledged Internet host.
Do I understand correctly that this will solve the problem?

[Chad Pilkey]

Putting your server on an external host might solve your issues. Depending on the host you might need to do the external firewall and dummy NIC steps. You also might want to try the bbb-install script which should do some of the extra configuration for you https://github.com/bigbluebutton/bbb-install. The options for the command are near the bottom of the page.

[implan...@gmail.com]

Hi, Chad!
Please help.
Now I configure my BBB on an external server with an external firewall configuration and a dummy NIC. It solved my problems.
All functions of the BBB is now working correctly.

But I have one problem.
I can't start broadcasting my webcam on my mobile phone and tablet. When I launch the webcam on my mobile phone, I get the error "webcam connection error".
But when I try to start broadcasting the camera on my computer. The camera works correctly. The webcam starts and broadcasts the video.
Clients running on a PC, you can watch the videos. But if the client connects via mobile phone, he sees a window for broadcasting video that is downloaded endlessly .

How to fix ?

[Chad Pilkey]

Can you try connecting to our test server and see if you can share your camera from your phone. https://test.bigbluebutton.org/demo/demoHTML5.jsp. Also what are the phone OS, browser, and versions for both?

[mohellebi mounir]

hello Chad,

i experienced the same issues, i m running on a kitkat Android 4.4 OS and a chrome browser. i can't share bith my cam and screen sharing. i tried to connect with 4G and ADSL connexion without success, i tried also with a 6.0 Android phone, same problems.

any help?!

best regards,

[Chad Pilkey]

Is this with our servers? Knowing that it's with our servers helps to eliminate server configuration errors. The cause of it not working might be in the browser console, but I'm not sure if you can get that from mobile browsers. I don't work on the WebRTC video stuff so the debugging is mostly out of my knowledge base.

[mohellebi mounir]

Yes Chad I'm testing on your server https://test.bigbluebutton.org and i have the same issues everytime. still waiting for some help from our dear Fred 😁.

thanks to you Chad.

Best regards,

[Fred Dixon]

Chad can help you as best an anyone else.  

> I tried also with a 6.0 Android phone, same problems any help?!

Are there any others here able to connect to 

  https://test.bigbluebutton.org/

and share audio/video with an 6.0 Android phone?

Regards,... Fred

[mohellebi mounir]

hello Fred,

i have no doubt about Chad or the rest of the team. you guys are doing an amazing job!!!! thanks you all.

best regards,

[implan...@gmail.com]

Hello, Chad. When I connect to  https://test.bigbluebutton.org/demo/demoHTML5.jsp my mobile webcam connects successfully.
What is the reason? How do I configure this on my server?
I'm testing on Android 6.0.1

[implan...@gmail.com]

and this error was also found in firefox.

Screensharing in firefox work correctly

[Chad Pilkey]

I don't know what the problem might be with the configuration, but it definitely suggests that the problem lies there rather than something with the phone or network.

[Paulo R. Lanzarin]

Hey guys, let's try to figure this out.
@mohellebi: Can you paste the output of bbb-conf --status? Also, pastebin the browser console logs when trying to share a webcam in your server.

@implatiumweb: To share your screen in Chrome in your own server, you'll have to deploy your own extension that whitelists your server's domain.

This is required by chrome by default. You can follow the steps listed in https://github.com/bigbluebutton/screenshare-chrome-extension.

And if both of you could pastebin the configuration files located in /usr/share/meteor/bundle/programs/server/assets/app/config/settings-production.json
and /usr/local/bigbluebutton/bbb-webrtc-sfu/config/default.yml, it'd be great. Let's try to find if it's a misconfiguration issue (it seems to be the case) and
how we can fix it.

Hello Chad.

I think I found the problem.

when I launch BBB and start streaming from the camera, I launch netstat-lnpt

this is the netstat -lptu output

tcp        0      0 10.10.50.141:26337      *:*                     LISTEN      23016/kurento-media

udp        0      0 10.10.50.141:30490      *:*                                 23016/kurento-media
udp        0      0 10.10.50.141:30961      *:*                                 23016/kurento-media

Hmmm?

My real internal ip adress is 10.10.50.140.

Now the camera is connected on all devices in the internal network.

The problem is observed when I connect from the Internet

How to change kurento-media ip adress???

Hey,

Have you set up a STUN server? Taking into account that your server is behind NAT, you need to configure
one on Kurento so it's able to fetch a valid IP address. 
If you've not done this yet, you might wanna take a look at http://docs.bigbluebutton.org/html/html5-install.html#2-install-html5-client 
and then retry your tests.

s,

Paulo.
