Hello,
I set up a hotspot system using external radius and external web server
the login is done through facebook.
I have put in the walled garden the facebook through walled garden and walled garden IP
*facebook*
*fbcdn*
It works like charm on all devices except Ipones/ipads (ios11).
When login with facebook it gets error: hotspot login cannot open the page because it could not establish a secure connection to server

Has anyone faced that? any help, please?

hi, minanaguib60
please try to add *doubleclick* , and *google* to your wall garden, it works like charm
