Comment 10 for bug 1065211

UPDATE:
I found the following post:

on a whim, I tried the curl command outputted bu the failing `nova --debug $ARGS`, to ensure the auth token/password is correct & to possibly try different passwords/tokens in the event they fail.

I simply ran those commands, none of them failed with a 401/404, so I ran the original command, and it seems to be working now.

I've not made *any* changes in my configs, so, despite the issue being seemingly OK, I'm still none the wiser as to *what* caused the issue or how to address it in future.

There were a few other options listed via `nova help | grep list` that failed before, that seem OK now
