Requirement
Activity completion depends on the BigBlueButton server sending live events back to Moodle, and on Moodle being configured to receive them.Enable it
- Log in as an administrator.
- Open the BigBlueButton plugin settings.
- Enable Register live events or the equivalent site option.
- Save the setting.

Test it
If your Moodle server is behind a restrictive firewall, the callback might not reach Moodle correctly. A simple test is:- enable live events
- create a test recording
- set a very low attendance threshold
- confirm that the completion signal is received and processed
