For the past week I was trying to configure an HTTPS server on a cisco 2900 router, I've used the following commands and assigned a username and password to privilege 15 however, when Im trying to access a given ip it requires a username and password however when I insert the username and password I configured it does not allow me to enter and i'm not sure where the problem is.

Router(config)# ip http secure-server

Router(config)# ip http authentication local

These were the commands i used for the https server and also I used the following to assign the username and password

Router(config)#username name privilege 15 secret 0 password

where 'name' and 'password' represent the username and password respectively

I'm trying to access the 192.168.14.1 interface on the router and the username and password i created are not authorized to enter

(I got the commands from a cisco router manual)
