cannot access user manager

i have my hotspot setup with user manager,I cant seem to access user manager using http://19.168.1.1/userman where 192.168.1.1 is my router ip..I already have subscriber created and router add on user manager,is there anythis that i missed?

Try to access User Manager by Public IP address of the router.

its ok,I can access it right now,its only the hotspot which is preventing me to access it,by disabling the hotspot or assigning different ip pool, I can access user manager
