When trying to start my Rails app in C9.io, I see the Socket Error below. I am unsure how to correct this issue. Any ideas?

  • ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-linux]
  • Rails 4.2.5

  • Cloud9 IDE

    blacknight659:~/jh_projects/mybay2 $ rails s -b -$IP -p -$PORT

I got the same error when tried to start my Sinatra app on cloud9. It turned out that I was running the command : $ bundle exec rackup -p $PORT -o $IP with root user (su). Try to run it on normal user.

You have a dash before ip and port arguments. The values of the arguments are specified without dashes. Try:

rails s -b $IP -p $PORT
