Urlopen error [Errno 111] Connection rejected for selenium python

Question

I try to exit the test page, but there is a connection failure error when you do driver.find_element_by_xpath ("// a [@ href = '/logged/pages/user/logout.php']"). click () I also tried linktext, or ActionChains, the same error. And this happens sometime, not always, Any comments?

Error message

This is a temporary connection problem between your Selenium language bindings and the Selenium server. This can happen more often if you use the remote Selenium server on another computer, and especially if it goes over the Internet. For example, we saw such errors when using remote selenium servers in BrowserStack or Sauce Labs browsers.

Since Python / Selenium bindings do not have an automatic way to re-request JSON wire (JSON over HTTP) requests / commands, you are forced to process it in your code. For example, if these are the tests that you perform, then the general way to eliminate these errors is to repeat unsuccessful tests 3 times, and only if all three attempts fail, report a failed test.
