After upgrading to OSX Yosemite, I can no longer test my app on a mobile device by using my development machine's (MacBook Pro) IP address. For example, I used to be able to view a Rails app on a phone by going to http://192.168.0.4:3000, but now I get the following error:
ERR_CONNECTION_REFUSED
I get the same error when testing an AngularJS app using the grunt server running at http://192.168.0.4:9000
Any help will be greatly appreciated.
It could help to bind the server to your local IP, like
rails s -p9000 -b192.168.0.4
to start your rails app
Consider giving a try to Pow. Its pretty simple to install, and a great solution to share a local development across multiple devices.
Like it explains in their homepage, you can install it with just :
curl get.pow.cx | sh. To prevent any errors, install in Terminal app outside a Tmux session.
And just symlink your app :
cd ~/.pow
ln -s /path/to/myapp
You can access your app at http://myapp.dev/, and at http://myapp.[your ip address].xip.io from another device.
Not a direct response to your issue, but an alternative to setting yourself a configuration in your preferences.
Turn IPv6 off. It Prevented me from connecting to my localhost from other computers on my LAN. And, with the newer versions of OSX there is no way to turn it off in the Network Preferences Panel so you have to do it from terminal.
Open Terminal and enter to turn it off:
networksetup -setv6off Wi-Fi
And this to turn it back on:
networksetup -setv6LinkLocal Wi-Fi
If you are connected via Ethernet or something else just run this command to list the available options:
networksetup -listallnetworkservices
and replace "Wi-Fi" with the appropriate device.
I don't have a mac, but that seems to be the server not accepting connections, if that is the case, it's only accepting localhost connections, try binding de server to accept all connections or bind it to 0.0.0.0 ip
Can you access that IP from Browser? are you sure your IP is in the same range with 192.168.0.4? It is your mobile device connected on the same network? Maybe you used internet sharing before update to Yosemite and now is off?
I think your IP address changed. Telnet from console(terminal) your I.P. port. If 192.168.0.4 is your real Ip then maybe add(as root or via sudo) an entry in /etc/host file an entry as 127.0.0.1 192.168.0.4. Restart network or reboot. Also you can try nmap ( on ip to see open ports). Nmap has been ported to OSX just google for installer.

I need some help accessing a server that I have running on my mac. So basically my setup consists of mac on which I'm running my server and also using XCode to run the app on an iPhone connected via USB. And then both this iPhone and the mac are on the same wiFi network which is a personal hotspot that I have running on a different iPhone. I'm trying to access localhost from the iPhone by basically using my mac's IP address and the right port: http://IPADDRESS:PORT/, however this doesn't seem to work. Any ideas as to what may be going on here and potential workarounds or solutions. Connecting to a non hotspot, traditional wifi network is not an option at the moment.
Thanks!
This will work if you have it set up correctly; I am doing it right now. Remember that you have to bind the server to 0.0.0.0 — not 127.0.0.1 — if you want to connect from non-localhost IPs. Also check your system firewall.
If you're still having trouble, Tailscale is another solution that may help — https://tailscale.com
I suggest you take a look at using ngrok as a solution, this will create a secure tunnel and expose the service running on your Mac through a url.
You'll need to create an account and retrieve your auth token.
You can then install it using Homebrew by running in Terminal: brew cask install ngrok
Once installed, connect your account by typing into Terminal: ngrok authtoken [auth_token]
To start a tunnel, type into Terminal: ngrok [protocol] [port number]
For example, to start a tunnel to a HTTP server running on your mac: ngrok http 80 (or ngrok http 443 for HTTPS)
If its a custom TCP protocol use: ngrok tcp [port] (or ngrok tls [port] if using TLS)
This will then give you a URL to use in your app. On free accounts, the URL will change on each restart, paid accounts get a static URL option.
If you don't have Homebrew, download it from and follow instructions on: https://ngrok.com/download
I have a server running on localhost:5000 on my desktop, and when I make http requests through my react-native app when running on the iOS simulation to it, it works. However, when I connect to a real device, the http requests don't work. What am I doing wrong? Is there something I have to configure?
localhost in your desktop is not the same ip of the localhost of your device.
Get the ip of your computer by typing ifconfig in a terminal, then replace localhost by this ip, you should type something like that in your device browser:
192.168.0.23:5000
Maybe my answer is too late but I ran into a similar situation today and I got it to work by running my node server using the IPv4 of my desktop and then making the request to that IP.
For example, I am running my nodejs development server at http://192.168.0.135:3000(local IP of my desktop) instead of localhost and then I make the fetch API request from my react-native app to http://192.168.0.135:3000/.
Just make sure your nodejs server and your app are on the same local network. My react-native server (metro bundler) is running on a separate PC also in the same wifi network.
If your are on macOS go to settings -> Wifi / and show more,
on bottom you see "IP address", it's your correct localhost for ios physical device !
I’m probably doing something stupid here, but....
I can’t access a rails app running on my Mac from a Windows 10 VM. I have set the network adapter to "Share with My Mac". I can access a PHP site running on my mac via http://[my-machine-name].local or http://[my-ip-address]. But if I specify port 3000 to view my rails app I get an error message (to the effect that [my-ip-address] refused to connect) even though the app is running. I don’t know if this is an issue at the Mac end (though my firewall is off for testing), the windows end, or to do with my VMWare network adapter setting. Any assistance gratefully received

Just use the -b flag while running your rails app like rails server -b 0.0.0.0:3000 so it gets bound to the whole network interfaces and it can be accessed from outside
I am trying to access my localhost of rails running project on my mobile device.
This is how I am trying.
http://ip:3000
But it says the webpage is not available.
I tried with another port as well and It doesn't work even there?
What's wrong here? I use to check earlier this way.
Please guide
Try running this code below to your server:
rails s -b 0.0.0.0
This worked for me!
Just give:
ip = your phone's ip address
(Check it in connection information if you are running this on Ubuntu)
ip:3000/your_page if you do not have mapped your root to some page.
Else ip:3000 will work if you have mapped root to some page.
Try it in Chrome and see as it doesn't need any http or https it automatically selects the required one.
Here is how I did it
Put both your computer and phone on the same wifi network
rails s -b 0.0.0.0
routerlogin.net (or however you access your router it will say on the back of router)
get attached devices to the router. Note your computers ip. Mine was 10.0.0.20
on phone go to 10.0.0.20:3000 (but use the ip for your computer from step 4)
For the first time since upgrading to OSX Yosemite, I need to view an app running on my machine from another machine on the same network. Previously, this was as simple as finding my internal IP address and using that with port 3000, eg. http://192.168.0.111:3000.
However, I am now finding that with Yosemite this doesn't work. The application is definitely running and is available via localhost:3000 but not via my internal IP.
I have run the network utility port scanner and it shows that localhost exposes port 3000 but my IP doesn't. Other machines on the network that have yet to upgrade (10.7.5 and 10.9.5) are not having this issue.
Any help would be greatly appreciated.
Edit: According to the security and privacy pane of the system preferences, the Yosemite firewall is currently off - so that isn't causing the problem.
By default, rails server will only accept connections from localhost. You can check this by looking at the console output:
Listening on localhost:3000, CTRL+C to stop
To listen on all addresses, which will allow you to connect from other machines on the local network, you must explicitly bind to a more permissive address. Try this:
rails server --binding=0.0.0.0
You should now see:
Listening on 0.0.0.0:3000, CTRL+C to stop
Now you can connect to your Rails app from elsewhere on your local network, by browsing to e.g. http://192.168.0.111:3000.
