Please check the url of the BigBlueButton server AND check to see if the BigBlueButton server is running.

[hakan güler]

Hello everyone,
I want to use the bigbluebutton and moodle.
I have installed them successfully. I have integrated my absolute number and password which I got from Bigbluebutton to my plugin in moodle.
It is all OK until now. There is no problem whilst connecting with the bigbluebutton's test host but when I try to connect with my own IP address, there is an error like this one:
"Unable to join the meeting. Please check the url of the BigBlueButton server AND check to see if the BigBlueButton server is running."

Please, help. Thanks

Hi hakan güler.

I have made it too, but didn't see that problem
Have you installed the Bigbluebutton and the Moodle with the same server?
If yes ( there is no way to use both with same server, so install bigbluebutton and moodle two different servers).

If no ( check that your bigbluebutton server is running then set ip to the BBB.) By using Sudo bbb-conf -- setip .......).

That is all my effort thanks.

Hi Hakan,

> but when I try to connect with my own IP address, there is an error like this one:

"Unable to join the meeting. Please check the url of the BigBlueButton server AND check to see if the BigBlueButton server is running."

It's likely one of two issues

1.  Is your Moodle server server able to make a direct HTTP request to your BigBlueButton server?

You can verify this by logging into your Moodle server and execute the following command

wget -O - --quiet http://bigbluebutton.server.com/bigbluebutton/api 

where "bigbluebutton.server.com" your BigBlueButton server.

This should resolve to:

<response><returncode>SUCCESS</returncode><version>1.0</version></response> 

2.  Is your BigBlueButton server properly running?

You can check by installing the API examples, see

  http://docs.bigbluebutton.org/install/install.html#install-api-demos

and check that you can login.  If not, then the BigBlueButton server may not be responding to API requests from the demo apps (this will give you the error message you see in Moodle).  Check the output of

  sudo bbb-conf --check

for possible issues.  

Regards,... Fred

Hi Hakan,

> # Not Running:  Nginx

This will prevent  BigBlueButton from responding to any incoming API requests as nginx acts as a proxy for tomcat 7.

Can you check the nginx log files in 

  /var/log/nginx

and see if there are any error messages.  Also, try to restart nginx itself

  sudo service nginx restart

to see if it will start.  The log files above are the first place to look.

Also, your BigBlueButton server looks to be on an internal network

> http://192.168.1.17/demo/demo1.jsp

Is your Moodle server able to make a direct HTTP connection to 192.168.1.17?

Yes Fred,

My Moodle serber able to make direct HTTP cpnnection to 192.168.1.17/moodle. This is run. But bbb not working.

Hi Haken,

> My Moodle serber able to make direct HTTP cpnnection to 192.168.1.17/moodle. 

This doesn't look right.  Are you trying to run both BigBlueButton and Moodle on the same server?  

If so, this is the cause of your problems (and explains why nginx is failing to load). For more information see

  http://docs.bigbluebutton.org/support/faq.html#we-recommend-running-bigbluebutton-on-port-80

So what should I do?

If Port 80 I just upload a bigbluebutton, Is that where should I install moodle ?

[Fred Dixon]

Hi Hakan,

The reason that Moodle is unable to connect to BigBlueButton is you've tried to install both on the same server.  They are both web-based applications that need to bind to port 80 (see URL in previous post).

To make it clear, we recommend you install BigBlueButton on a dedicated server that has port 80 free.  We also recommend do not attempt to install other web-based applications (such as Moodle, plesk, etc.) on the same server which is running BigBlueButton.  Doing this it leads to (subtle) resource conflicts that manifest themselves as error messages, which leads you at first to believe that something is wrong with BigBlueButton but, in reality, it's a resource conflict that has prevented BigBlueButton from running.  

Regards,... Fred
