Some user at MA5200 can pass forced WEB authentication before, one day he cannot but other users can use, why?
User sets proxy server. When user do it, forced WEB authentication is unavailable (exceptMA5200F PNP users).
There are many reasons about the failure of forced WEB authentication. First make sure that the machine can obtain IP address. And then person who enters WEB server first can open webpage or not. Check whether WEB server and route is normal or not. If webpage can be open, enter another IP address to check whether DNS is normal or not. If it cannot enable forced authentication, the configuration is problematic. If it can but cannot when entering domain, DNS or route to DNS is problematic.
