Why is my userman not counting?

My userman does not take note of time used, download traffic, upload traffic, time left and all other accounting stuff for users.
At first I taught it was license restriction and I upgraded to L6 but yet it persisted.
As users log in and out no accounting is performed
My hotspot users expire at a particular uptime but now most of them do not expire since there is no accounting as they log in and out.
Pls what could be the problem?
Find attached my screenshots.

What version of MT are you using? Is it stable or BETA?

ROS 4.17

You sholud set Src. Address in Radius settings (radius.png screenshot) to 0.0.0.0
