Unemployed operations do not work inside Sinatra route

I use stones headlessand selenium-webdriverto activate the browser without the Firefox browser:

headless = Headless.new(
  video: {
    frame_rate: 12,
    codec: 'libx264'
  }
)
headless.start
driver = Selenium::WebDriver.for(:firefox)

With this code, I can write the following:

driver.navigate.to("http://google.com")

However, the following message causes an error after visiting "/" in the browser:

get '/' do
  driver.navigate.to("http://google.com")
  erb :root
end

The error is as follows:

*** Errno::ECONNREFUSED Exception: Failed to open TCP connection to 127.0.0.1:7055 (Connection refused - connect(2) for "127.0.0.1" port 7055)

I am sure that this is because it is driver.navigatenot called in the headless area, so it cannot connect to the Firefox instance.

I also tried using the modular style of the sinatra, but the same error occurred.
