Captive portal attached to an interface but after authentication browser go loop

Hi all,
 I have attached a Captive Portal to my lan interface with a local group authentication.
 
From a pc client, when I open the browser for digit any website, the Fortinet login appear (correct)
 
I insert my username and password (correct)
 
Fortigate accept my credentials because I can see my user from "Monitor" -> "Firewall User Monitor" (correct)
 
the problem is now because in address bar of the browser, I can see a continuous loop of the address:
 
http://172.16.0.X/fgtauth?092321232323cdw2
http://172.16.0.X/fgtauth?021372123435ed82
http://172.16.0.X/fgtauth?010032723341c889
http://172.16.0.X/fgtauth?0933423487fd0fc44
 
and the website that I asked don't open.
 
Also if I open another tab in Chrome, I can see the same loop with the magic token that change continually.
 
Can I solve or debug this big problem?
 
I haven't found any documentation about diagnostic of Captive Portal feature.
 
thanks!
Andrea

    same here.  we use this more than you'd think to provide limited access to back end systems.
     
    any leads on workarounds?
