Web interface broken after upgrading apache to 2.2.16

[Salam Y. ELIAS]

I have monit up and running since 3 days.
Tonight I upgraded to Apache 2.2.16, rebooted my machine and since ever
I am not able to browse the website at port http://mylinux:2812 anymore
using my machine name, I an getting 
****************************
Unable to connect
Firefox can't establish a connection to the server at salamlinux:2812
***************************

Checked monit status everything was up and running.

I browsed with http://localhost:2812 it worked


Whenever I try using the machine name, in http error log I get 

[Tue Nov 09 02:33:48 2010] [notice] SSL FIPS mode disabled

mod_perl/2.0.4 Perl/v5.10.1 configured -- resuming normal operations

Any idea why this is happening because I need to access monit from other
machines.

Thanks
