Error while switching windows using Selenium Webdriver

Question

I've written a Ruby script to automate some user operations using IE. I'm using Selenium Web Driver for IE. Below is my code.

require 'selenium-webdriver'

browser = Selenium::WebDriver.for :ie

first_window = browser.window_handle
browser.switch_to.frame(browser.find_element(:id=> 'outerFrame'))
browser.switch_to.frame(browser.find_element(:id=> 'innerFrame'))

table_rows = browser.find_element(:id=> 'AllItems').find_element(:tag_name=> 'table').find_elements(:tag_name=> 'tr')
count_cell = table_rows.at(table_rows.length-1).find_elements(:tag_name=> 'td').at(1).find_element(:tag_name=> 'a')
count_cell.click

sleep(5)

all_windows = browser.window_handles
new_window = browser.window_handles.last

browser.switch_to.window(new_window)

btn = browser.find_element(:id=> 'btn_export')
btn.click

At one point, after clicking a button, a new page is opened. Now, when I try to switch to the new window, I get the following error.

C:/Ruby21/lib/ruby/2.1.0/net/http.rb:879:in 'initialize': No connection could be made because the target machine actively refused it. - connect(2) for "127.0.0.1" port 5555 (Errno::ECONNREFUSED) from C:/Ruby21/lib/ruby/2.1.0/net/http.rb:879:in 'open' from C:/Ruby21/lib/ruby/2.1.0/net/http.rb:879:in 'block in connect' from C:/Ruby21/lib/ruby/2.1.0/timeout.rb:75:in 'timeout' from C:/Ruby21/lib/ruby/2.1.0/net/http.rb:878:in 'connect' from C:/Ruby21/lib/ruby/2.1.0/net/http.rb:863:in 'do_start' from C:/Ruby21/lib/ruby/2.1.0/net/http.rb:852:in 'start' from C:/Ruby21/lib/ruby/2.1.0/net/http.rb:1375:in 'request' from C:/Ruby21/lib/ruby/gems/2.1.0/gems/selenium-webdriver-2.48.1/lib/selenium/webdriver/remote/http/default.rb:107:in 'response_for' from C:/Ruby21/lib/ruby/gems/2.1.0/gems/selenium-webdriver-2.48.1/lib/selenium/webdriver/remote/http/default.rb:58:in 'request' from C:/Ruby21/lib/ruby/gems/2.1.0/gems/selenium-webdriver-2.48.1/lib/selenium/webdriver/remote/http/common.rb:59:in 'call' from C:/Ruby21/lib/ruby/gems/2.1.0/gems/selenium-webdriver-2.48.1/lib/selenium/webdriver/remote/bridge.rb:664:in 'raw_execute' from C:/Ruby21/lib/ruby/gems/2.1.0/gems/selenium-webdriver-2.48.1/lib/selenium/webdriver/remote/bridge.rb:642:in 'execute' from C:/Ruby21/lib/ruby/gems/2.1.0/gems/selenium-webdriver-2.48.1/lib/selenium/webdriver/remote/bridge.rb:216:in 'switchToWindow' from C:/Ruby21/lib/ruby/gems/2.1.0/gems/selenium-webdriver-2.48.1/lib/selenium/webdriver/common/target_locator.rb:81:in 'window' from script.rb:18:in ''

I tried my bit to resolve the error, by modifying firewall and added rules for port 5555. Even then issue persists. I found some already exsting questions on this, but most of them are related to Java or .Net. How can I resolve this error? Can anyone point me in the right direction?

The site is IE specific. It does not open on other browsers. — dr_dev
before clicking and going to new window save the wnidow handle of 1st webpage then click and after your operations are done use saved window handle to come back to original screen — Umesh Kumar
I am doing the same currently. "count_cell.click" is the step, where it opens a new page. — dr_dev
If you could provide a bit of html/css/js to reproduce the issue it might help us debug. The most simple example that can reproduce it. — snowe

I am not a ruby expert, but I have seen similar problems happening. I have a Python-ic solution. All you need to do is Ruby-fy the code. https://gist.github.com/ab9-er/08c3ce7d2d5cdfa94bc7

def change_window(browser):
    """
    Simple window switcher without the need of playing with ids.
    @param browser: Current browser instance
    """
    curr = browser.current_window_handle
    all_handles = browser.window_handles
    for handle in list(set([curr]) - set(all_handles)):
        return browser.switch_to_window(handle)
