I have to reset my router (RB951Ui) in today with basic configuration, but strange problem is the hotspot page can't work any more, the IE say "404 error, can't find the page", it's happened when I open any outside website, but hotspot on the gateway IP address "172.16.0.1" is working


below is my configuration, sincerely thanks

I'm forgot to post the hotspot working on gateway when I add it in walled garden IP list. but can't work when I try to open any outside website.

I think something wrong/missing in my configuration, but I can't find it.

did you change something in the hotspot html files? renaming, moving, deleting?

No, I try to reset all of my router with default settings, and hotspot folder created by system automatically.

problem resolved, I have type the wrong DNS, now change the DNS server to local gateway in DHCP server, and it's working, Thanks everyone.
