Hi, My app won' t open to localhost:3000. It only opens when I use 0.0.0.3000. Why is that?

Mine was the same on the Mac. It used to work with localhost:3000 but then I had to switch to using rails server -b 0.0.0.0:3000 to get it to work.

No idea why, so I hope someone can provide an answer!

Steve.

Check this out, it may help. http://stackoverflow.com/questions/1478747/why-does-ruby-on-rails-use-http-0-0-0-03000-instead-of-http-localhost3000

Interesting, thank you. I'll try the --binding 127.0.0.1:3000 option next time I run the server.
