Authent windows dont auto pop-up when hardtime release

[nhimcoi30889]

Hi guys,

Im using pfsense 2.3.2 and captive portal. I config captive portal and its working well. But it has a problem as:
When clients release hardtime, End-user need open browser for re-authent (or turn off/on wifi) . But a lot of User dont know that (exam using fb applicaiton) and cant connect to internet.
How to force pop-up connection windows for this case?
Tks,
my eng is bad. :(

Really no good way, it's up to the client to notice.
