When I try to log out from the testing page, there occurs an connection refused error. This is the command / code I've used:

driver.find_element_by_xpath("//a[@href = '/logged/pages/user/logout.php']").click()

I also tried by linktext, or ActionChains, the same error. And it happens sometime, not always, Any comments?

The Error Message:

<urlopen error [Errno 111] Connection refused>

This is a temporary connectivity issue between your Selenium language bindings and a Selenium server. This may happen more often if you are using a remote Selenium server on a different machine and especially if it goes over the internet. We've, for instance, seen this kind of errors when using remote selenium servers at BrowserStack or Sauce Labs.

Since Python/Selenium bindings don't have an automatic way to retry JSON wire (JSON over HTTP) requests/commands, you are forced to handle it in your code. For instance, if these are tests you are executing - a common way to tackle these errors is to retry failed tests 3 times and, only if all 3 attempts fail - report a failed test.
