How do I connect using browser to router's IP address

I’m using RouterOS 6.40.5 and the RouterBOARD 750G r3.
I have the default setup with Ip 192.168.4.1 assigned to the router and the dhcp 192.168.4.10-100.
I can connect from the windows box using IP 192.168.4.1 to winbox. If I try to use the same IP in a browser it doesn’t connect. What or how do I enable login using browser from within the lAN using router’s IP?

If you can access WinBox, then go to:
IP > Services > www
You can set up port number, IP range allowed to access (leave untouched if you want to have acceess from any IP), and enable or disable.

That worked.
