    Just to get a bit more info, are you getting that error when you are going to domain.com in your browser?

    Or where exactly are you receiving the error message, in browser, terminal, etc.:
    error `127.0.0.1' is not a valid domain

@moisey I am getting the error in the application logs ie. unicorn.stdout.log

    Can you provide the output of the error log?

    Also what do you have in your /etc/hosts file?

      @moisey Thanks for helping.

      I get this in this the logs:

      Started GET "/" for 127.0.0.1 at 2019-07-19 20:34:47 +0000
      Processing by HomeController#index as HTML
      "user time zone: "
      Fri, 19 Jul 2019 13:34:47 PDT -07:00
      "127.0.0.1"
      Completed 500 Internal Server Error in 2ms

      PublicSuffix::DomainInvalid (127.0.0.1' is not a valid domain):
      app/controllers/application_controller.rb:72:in      setdomainvariable'

      The /etc/hosts file has the default settings:
      127.0.0.1 localhost

      The following lines are desirable for IPv6 capable hosts

      ::1 ip6-localhost ip6-loopback
      fe00::0 ip6-localnet
      ff00::0 ip6-mcastprefix
      ff02::1 ip6-allnodes
      ff02::2 ip6-allrouters
      ff02::3 ip6-allhosts
      ~

      ~

        So the relevant line:

        PublicSuffix::DomainInvalid (127.0.0.1' is not a valid domain):
app/controllers/application_controller.rb:72:insetdomainvariable'

        Which means that on line #72 of your application_controller.rb you have an error.

        Specifically you are calling PublicSuffix::DomainInvalid which is used to check if you have supplied a valid domain suffix like .com, .net, etc, but it looks like you are passing in 127.0.0.1 instead of a domain name, which isn't a valid domain name and as a result it doesn't have a valid DomainSuffix and that's why you are getting that error.

        If you have a configuration file for this app, it probably has 127.0.0.1 listed somewhere and you should replace that with the expected domain. But really it's a code issue not a deployment issue or configuration of your webserver, ruby on rails, etc.
