401 unauthorized:

Working:

oddly enough, also working

Seems from my testing that setting maxwidth=0, maxheight=0 on videos marked as unlisted can cause 401 unauthorized to appear. If a value > 0 is used on the same url, the problem doesn't manifest, nor does it manifest of listed videos (in my testing).

I had the same problem and I noticed it was the option "allow embedding" not checked. This should solve the problem.
