Return URL error

hi

The ‘return URL’ set to the hotspot login page does not seem to work properly for my windows IE, Firefox or Safari; ‘page can not be displayed’ error or 501/505 error. It does seem to work for UBUNTU Firefox with a ‘returning to non-secure page’ message. Is there something I have misconfigured?

thanks

What is the url, that you are typing to the web-browser ? (with HTTP or without, or even HTTPS ?)
