I tried to connect localhost:3000 in windows

rails server is running in vagrant(ubuntu 14.10)

portforwarding is done

when, I tried lynx 127.0.0.1:3000 in ubunutu, it works

but, in windows, I can't connect localhost:3000, 127.0.0.1:3000 too

just showed ERR_CONNECTION_REFUSED

in cmd, I ran netstat -t result is :3000 TIME_WAIT

how can I solve this problem?

this is my 'Vagrantfile'

edit: I tried to Host-only network adapter and I tried to connect 192.168.33.10:3000 in host machine still can't connect. One weird thing, I can send Ping to 192.168.33.10 in host machine and reply was came. I don't know what the problem is. I confused. somebody help me, please :(

  • are you trying to connect to your rails application running in your ubuntu from your windows environment? if so they are not the same localhost...determine the ip of your ubuntu on the network Commented Dec 23, 2014 at 20:09
  • @LoganMurphy In some webpages for vagrant, I saw vagrant portforward in automatic. and I insert line config.vm.network "forwarded_port", guest: 3000, host: 3000 in Vagrantfile Commented Dec 23, 2014 at 20:15
  • @LoganMurphy but I can ssh connect to ubuntu localhost:2222. if it possible, I think localhost:3000 can reacheable too. Commented Dec 23, 2014 at 20:18
  • you need set port forward in Vagrantfile. Show us your Vagrantfile Commented Dec 25, 2014 at 12:19
  • @BMW I added my 'Vagrantfile', please check it, thank you Commented Dec 26, 2014 at 14:28

Reset to default

The solution is running the code below to start your server:

rails s -b 0.0.0.0

I found this solution from another post about same problem. The answerer said 'You'll want to make sure that the server is binded to 0.0.0.0 so that all interfaces can access it."

I hope this post helps people who encounter the same problem :)

It actually should be rails s -b 0.0.0.0, "b" stands for "bind"
What a surprise... I always thought that rails server listens on all interfaces by default unless specified. There is a good answer showing how to achieve this behavior: stackoverflow.com/questions/28668436/…

You can find the reason in here: http://edgeguides.rubyonrails.org/4_2_release_notes.html

Due to a change in Rack, rails server now listens on localhost instead of 0.0.0.0 by default

If you want to use rails s instead of rails s -b 0.0.0.0, you can edit /config/boot.rb:

ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../../Gemfile', __FILE__) require 'bundler/setup' if File.exist?(ENV['BUNDLE_GEMFILE']) require 'rails/commands/server' module Rails class Server alias :default_options_alias :default_options def default_options default_options_alias.merge!(:Host => '0.0.0.0') end end end

shilovk's answer at stackoverflow.com/questions/27799260 is a little better as it accounts for environment

Also I have done something like this so that Guard starts this way: guard 'rails', force_run: true, host: '0.0.0.0' do watch('Gemfile.lock') watch(%r{^(config|lib)/.*}) end
