Capybara/Selenium gets a Net::ReadTimeout randomly on location.reload()

It turned out this wasn't exclusive to doing a location.reload() in JS. It sometimes happened just visiting a page.

The solution for me was to create an HTTP client for the selenium driver and specify a longer timeout:

Capybara.register_driver :chrome do |app|
  client = Selenium::WebDriver::Remote::Http::Default.new
  client.read_timeout = 120

  Capybara::Selenium::Driver.new(app, {browser: :chrome, http_client: client})
end
