set Rails environment url for selenium remote - ruby-on-rails

Question

I got selenium remote configured and running. I can access my development server (deployed with 'rails s') on '192.168.1.23:3000' from my computer using test methods like 'visit root_path' on capybara with minitest.
However, when I close my development server, I can't access my test server while testing, I just get a chrome error with page not found
test file:
require "test_helper"
feature "dashboard" do
scenario "test1", :js => true do
#Rails.application.routes.default_url_options[:host]= 'http://192.168.1.23:3000'
visit root_path
end
Note: activating line 4 gives me nil when running visit root_path
test_helper.rb
Capybara.configure do |config|
config.default_host = 'http://192.168.1.23:3000'
config.app_host = 'http://192.168.1.23:3000'
end
I've also tried
test environment, test.rb
Rails.application.default_url_options = {:host => "http://192.168.1.23:3000" }
Rails.application.routes.default_url_options = {:host => "http://192.168.1.23:3000" }
Edit:
I have rails server configured to listen to external addresses:
boot.rb
#this lets listen to some interfaces,
#https://fullstacknotes.com/make-rails-4-2-listen-to-all-interface/
require 'rubygems'
require 'rails/commands/server'
module Rails
class Server
alias :default_options_bk :default_options
def default_options
default_options_bk.merge!(Host: '192.168.1.23')
end
end
end

By default Capybara runs the application on a random port, but you've set app_host to only connect on port 3000 (Which is the dev server default). Rather than setting a fixed port in app_host set
Capybara.always_include_port = true
Capybara.app_host = 'http://192.168.1.23`
Then if the random port assignment isn't working due to firewall issues between your selenium remote and local machine you can set
Capybara.server_port = <some fixed port number the test app will get run on>
