I also proposed the alternative to connect over the IP 192.168.3.1
The http:// got added because of the www. Locally connecting normally is without http:// (at least on my linux). To resolve the Omega-ABCD.local/ name you need on Windows Bonjur and on Linux Avahi running.
Linux users can check withavahi-resolve -a 192.168.3.1 192.168.3.1 Omega-ABCD.local
if the avahi-daemon is running.
