You are having intermittent problems communicating with our Auth server. We do not suspect anything on your end, as that would cause complete failure in communicating with our servers. There are no known problems at our end. If it were, the forum would easily have thousands of posts about this topic, instead of a handful. It is mostly likely a regional thing in an intermittent hop between you and us. There is nothing either of us can do about this situation, and you'll just need to ride it out.
