Can't map local ip address to localhost

Question

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 10.11.1
• Google 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                                                                                                               
PING 192.168.1.34 (192.168.1.34): 56 data bytes

64 bytes from 192.168.1.34: icmp_seq=2 ttl=64 time=0.138 ms

the mac and the phone are connected to the same wifi

Answer 1

I think it's an issue with Rails not accepting connections from outside except localhost.

Please try the following :

Allow public connections to local Ruby on Rails Development Server

The simplest way requires no additional installations: just add a single option to your rails server (or rails s) command when you start up the server:

rails s --binding=0.0.0.0

The 0.0.0.0 address means "listen to requests from anywhere." On many systems, the default is 127.0.0.1, which means "listen to requests from localhost only." (If you don't also specify a -p or --port option, then the port shall be 3000, as usual.)
