Server not running, tcp's server IP address could not be found


#1

Hi, I’m starting M Hartl’s tutorial and can’t get the server to run.

rails server -b $IP -p $PORT
=> Booting Puma
=> Rails 5.1.6 application starting in development
=> Run rails server -h for more startup options
Puma starting in single mode…

  • Version 3.9.1 (ruby 2.4.0-p0), codename: Private Caller
  • Min threads: 5, max threads: 5
  • Environment: development
  • Listening on tcp://0.0.0.0:8080
    Use Ctrl-C to stop

All I see is:

This site can’t be reached

tcp ’s server IP address could not be found.

ERR_NAME_NOT_RESOLVED

Any help would be greatly appreciated since this is the very first step, I can’t go further. Thanks!
