Web interface does not work when using hostname instead of localhost

[Salam Y. ELIAS]

I have monit up and running since 5 days.
When I type http://localhost:2812, I have a very nice interface.
However, when I type http://mylinux:2812 it doesnt respond, even when I
use the IP address it does not respond

I followed all instructions in the doc and wiki it seems to me that
there is no error, even opened port 2812 in my iptables.

Here is my config :


set httpd port 2812 and use address mylinux
allow localhost
allow mylinux
allow 192.168.1.2
allow 192.168.1.0/255.255.255.0
allow 192.168.0.0/255.255.255.0
allow admin:monit


even I added the following directive 
set http://monit:address@hidden:8080/collector

but no way, only localhost respond.

Thanks for your help
