Hi Penguas,
Are you using the BBB Moodle plugin? If so do you have it configured correctly, make sure your Security Salt for your BBB server is configured correctly.
The salt can be found in this file: /var/lib/tomcat6/webapps/bigbluebutton/WEB-INF/classes/bigbluebutton.properties
Look for the line that says: beans.dynamicConferenceService.securitySalt=<value_of_salt>
