Can not access hotspot or Login hotspot page

Hello everyone and warm greetings,
Basically I have a problem please help me, I have configured Hotspot and Usermanager on my CCR1009 8G router
when I want to open hotspot address by IP or DNS (asef.org) i can not open the page it gives error 404

Go to ip >> service and check that “www” is not disabled, by default it should be enabled and set to 80.

Then type in the local IP of your hotspot interface or public ip of the router with the www port.

So - http://(public-ip OR local IP):80
