Images not loading in screenshot

[jjfrey]

Hey Guys,

I'm running a Micro EC2 instance on AWS using Ubuntu 16.04.2 and while the CSS is loading correctly, the images aren't. I'm almost certain that there are incoming ports that need to be allowed incoming traffic, but don't know which ones without allowing all incoming traffic. Any ideas suggestions as to which ports should be allowed?

Actually as a follow up, I've opened up all ports on the server and I'm experiencing the same result. Has anyone else run into this kind of issue?

You should leave outgoing open and filter only incoming connections. Many websites are implementing some protections against hotlinking and robots, for example banning by user agent header or by IP address. Have you tried with another website or to run test from another location?

@vitalie I've tried with multiple sites with inconsistent results. However I am now seeing two images created when creating the screenshot, one is rendering correctly and one without images.

class ScreenShotService

  def self.with_login(options)
    ws = Webshot::Screenshot.instance
    ws.start_session do
      if options[:login_url]
        visit options[:login_url]
        fill_in "#{options[:user_selector]}", :with => options[:user_name]
        fill_in "#{options[:password_selector]}", :with => options[:password]
        click_button("#{options[:submit_button]}")
      end
    end.capture options[:url], options[:filename], width: options[:width], height: options[:height], timeout: 3
    return true
  end
end
