identifi captive portal doesnt redirect authenticated users succesfully to welcome page

[Eloy_Acosta]

Hi there, i have an external captive portal configured, so long so good, the issue is...
when the user gets authenticated the system doesnt succed to redireto to the "welcome page"
on the section "redirect from external captive portal" i have set Send succesfull Login to "Custom specific url"

Most of the phone log in succesfully but the only message they get come form the system a red letter message saying
"you have beeen succesfully authenticated please refresh your browser or close your browser and start a new session if you cant access the network"

if you siconnect and connect from the wifi you have access to the internet, you are authenticated.

what could be possibly wrong???

However the iphones seems to handle it ok (all of them)
