I cannot reach http://localhost:3000 after starting Ruby on Rails
server when running Windows 8. After running rails server in the
directory that I want the server to start, the following prompt shows
up:
C:\Users\Brian\railsapp>rails server
=> Booting WEBrick
=> Rails 3.2.13 application starting in development on
http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

C:\Users\Brian\railsapp>
After going to Internet Explorer 10, I tried to access
http://localhost:3000,
and I got a “This page can’t be displayed” error. I tried doing
“telnet localhost 3000” in the Command Prompt, and I got a “Could not
open connection to the host, on port 3000” error. I also tried
modifying C:\Windows\System32\drivers\etc\hosts, removing the # symbol
for one of the “localhost” entries, but I still could not access
http://localhost:3000. Please help me with this issue. Thank you.
