Problem with user access !

Hello everyone
In this time i have problem with hotspot and usermanger server,
In usermanger server created before long time users like 100 user for example so when i connected to hotspot and write username and password like “netc3r and password 4rx” the user can login direct without any problem! the “netc3r” have profile 12hour, The user need to logoff after that when the same user need to login in hotspot webpage with same username and password he cant login and webpage write “no valid profile found”? After that I checked the user in usermanger and the user valid time can login and access without problem but i see in status of user “netc3r” in usermanger:
status
“Start & Stop & interim & close” Whats mean of that?
Or how can i solve the problem please?
Thanks

No valid profile found means that the profile has been either expired because of reached uptime limit or because profile validity has ended.
So what are the limitations you ve added in the specific user profile?

The user have profile limitation “12hour” mean uptime 12hour
The user used only 20 min.? the user can login and access buz have more free time!
Knowing this situation was repeated more than one user,
I think the problem in PAP and https or ?

Any help?
