Google Drive Could not authenticate?

[pbc]

Just received an odd error on my N5 when I woke up this morning, simply says "Google Drive could not authenticate. Please check your account settings.".

Yet when I swipe the window out, then enter Google Drive, everything appears fine (I see a couple of my files in there). Further, there is nothing in "Settings" in Drive that actually allows me to check the account settings?

Anyone else receive this error?

I've seen this before, but never thought much about it since it's always working when I access it.
