Hello, dear webdevelopers!

I have a question.

I performed a clean install BigBlueButton 1.0 on Ubuntu 14.04 64-bit server.

This is what shows the command in the terminal:

$ Sudo bbb-conf --clean

$ Sudo bbb-conf --check

BigBlueButton Server 1.0.0 (1012)
                    Kernel version: 4.2.0-27-generic

/var/www/bigbluebutton/client/conf/config.xml (bbb-client)
                Port test (tunnel): 62.76.45.174

                    websocket port: 5066
                    WebRTC enabled: true

                       server name: 62.76.45.174
                              port: 62.76.45.174:80

/usr/local/bigbluebutton/core/scripts/bigbluebutton.yml (record and playback)
                     playback host: 62.76.45.174




** Potential problems described below **

After that, I needed to change the exact IP address to the host. I did

bbb-conf --setip my-site.com

and then I made

$ Sudo bbb-conf --clean

$ Sudo bbb-conf --check

but the error comes out at this point:

BigBlueButton Server 1.0.0 (1012)

# IP does not match:
#                           IP from ifconfig: 62.76.45.174
#   /etc/nginx/sites-available/bigbluebutton: my-site.com

That is, if I change the IP address on the host, an error occurs

I will thank you for the help!

Hi Rustam,

Note the warning says "Potential problems"

> ** Potential problems described below **

> # IP does not match:

> # IP from ifconfig: 62.76.45.174

> # /etc/nginx/sites-available/bigbluebutton: my-site.com

It's OK if the IP does not match -- bbb-conf is doing a simple check against the IP address and the value defined in bigbluebutton (in nginx). If you set it to a hostname, the match will fail, but BigBlueButton should still work correctly (assuming the hostname resolves to the IP address).

Hence, you can ignore this warning.

Regards,... Fred

Hi Fred,
I'm having the same problem of Rustam.
I have followed the steps to change my bbb server to be used with a domain instead of the IP looking to follow the steps to enable https protocol and get rid of all the anoying messages of Chrome.

This is the result of bbb-conf --check:

It's solved now.
It was a lack of defining the domain in the server, once added it started to work as expected.

I am also facing the same problem. It would be very great of you if you could guide me to resolve the problem and please let me know
how to define domain in the server.

Hi Rakesh,

> I am also facing the same problem.

Are you getting a 500 error when you try to access the API demos on your BigBlueButton server?

Hi Rakesh,

It looks like you are behind a firewall, but none of the configurations for running BigBlueButton behind a firewall have been applied.

We would recommend installing the latest build of BigBlueButton 2.0-beta. The following script will help you with the setup, install a SSL certificate (from the good folks at Let's Encrypt), and configure BigBlueButton to work behind a firewall. See

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

You'll still need to open the necessary ports on your firewall (if there is one in effect).

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

Regards,.. Fred

It also looks like you've got a SSL certificate issue. When I go to your site my browser throws warnings because the certificate is for a different domain.

It looks like you've got a couple of audio configurations incorrect so I would expect audio to not work.

For the SSL problem it looks like your certificate chain is incomplete. This is a handy site that can analyze a server's SSL setup. https://www.ssllabs.com/ssltest/analyze.html?d=virtual.usfx.bo&hideResults=on
