Cannot connect to Localhost:3000 for Rails but 127.0.0.1:3000 works
localhost, port, ruby-on-rails
Solution
Please check your host file. I assume you are using ubuntu then just type
sudo nano /etc/hosts
If the below line exists then ok else just insert the line.
127.0.0.1 localhost
And use localhost:3000 not Localhost:3000
Problem
I am learning Ruby on Rails with railstutorial.org and met this strange problem. I ran "rails server" and the following information showed: ``` => Booting WEBrick => Rails 4.0.4 application starting in development on http://0.0.0.0:3000 => Run `rails server -h` for more startup options => Ctrl-C to shutdown server [2014-04-02 01:28:18] INFO WEBrick 1.3.1 [2014-04-02 01:28:18] INFO ruby 2.0.0 (2014-02-24) [x86_64-darwin12.5.0] [2014-04-02 01:28:18] INFO WEBrick::HTTPServer#start: pid=13004 port=3000 ``` I try connecting to localhost:3000 on various browsers and they all cannot establish a connection to the server. I also tried rails server -p 3001 and connect to localhost:3001, which failed as well. However, I tried 0.0.0.0:3000 , 127.0.0.1:3000, both of them worked and rendered the default welcome for rails. Then I tried localhost:80, which successfully told me "It Works" and I can actually connect to my another local project using PHP+Apache. So I really wonder why this happens and could anyone possibly give me any hint on it. Thank you in advance:)
