Accessing site problem

Hi,

I'm having problems accessing an nginx hosted site. On the server hosting the site, i can ssh in and run;

w3m http://localhost/mysite

And everything works OK

But when i try to access the sitre from another machine on the same network via a browser i get 'can't establish a connection to the server at xxx.xx.x.xx'

I'm able to ping the server and connect via PuTTY etc

Any help working out what could be wrong appreciated.

Thanks.
