I Have 2 applications:
- a rails api running on my mac like this: 
rails s - an android client app talking with the rails api from mi phone
 
Well, the apps are not talking yet...
I'm trying to perform a POST to http://192.168.1.34:3000/api/uploads from the device, but I'm getting ERR_CONNECTION_REFUSEDon chrome.
So, I try to execute the same request from the computer and it returns the same ERR_CONNECTION_REFUSED.
When I execute http://localhost:3000/api/uploads, from the computer it works fine.
So, I think the local ip is not mapping to localhost. How can I do this?
I' using:
OSX El Capitan 10.11.1Google Chorem Version 48.0.2564.23 beta (64-bit)
this is how my /etc/hosts file looks like:
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1       leansmac
127.0.0.1       localhost
255.255.255.255 broadcasthost
::1             localhost
ping it's working too:
ping 192.168.1.34
