When I try to run my rails app using
RAILS_ENV=production rails s -binding=128.199.95.219
I get this error

I've googled many places but still find no definite answer which could solve this problem.
My app is running in Ubuntu (14.0.4) with Nginx and Unicorn at DigitalOcean
Any idea anyone?
Use a double dash for the binding parameter, i.e.:
RAILS_ENV=production rails s --binding=128.199.95.219
See rails s --help for more info.
