Behat After scenario

I am learning a behat tool. When I pass the particular behat scenario like this:

php bin/behat --name "Rating widget appears on Blog page when enabled"

when I run the scenario is run properly but after scenario give the error like this:

This server could not verify that you are authorized to access the document requested. Either you supplied the wrong credentials (e.g., bad password), or your browser doesn't understand how to supply the credentials required.

So how can I solve this problem ?
