Hi Subrhi,

Can you post the output of

  sudo bbb-conf --check

Also, did you get any errors during the installation?

Regards,... Fred

Hi Surbhi,

> http://192.168.1.6/default.pdf

The default presentation isn't accessible.  

Are you running another web server?  BigBlueButton installs nginx, but you will have problems running it if you already have another webserver running (such as apache2).

Python is not installed by BigBlueButton.  Try shutting down your python application and restarting BigBlueButton.  We recommend installing BigBlueButton on a clean server (no other web applications running) as there are possibilities for conflict.

Hi Subrhi,

We recommend not running BigBlueButton on the same server with other web-based applications.  For reasons why, see

Hi Surbhi,

Yet the file

  http://192.168.1.6/default.pdf

is not available via HTTP request.  Can you check that the file

  

  /var/www/bigbluebutton-default/default.pdf

exists.  The output of netstat shows nginx is listening on port 80 -- did you make any changes to the nginx configuration or did you have any errors when installing BigBlueButton?

Hi Surbhi,

Thanks for giving me a chance to take a closer look at your setup.  It appears you've installed edX on the same laptop as BigBlueButton.

The problem is that edX is using nginx with it's own configuration files.  It looks like you had installed BigBlueButton after the installation of edX, which means that edX had already configured nginx to serve its files.

We recommend you install BigBlueButton on a clean Ubuntu 14.04 64-bit server that does not have any other programs installed.

This way, there won't be any subtle conflicts that prevent BigBlueButton from running correctly.

Regards,... Fred
