[Hummingbird] Hummingbird not returning results

Hi,

I'm continuously getting the following result for every time I try to run a performance test on my devel site using Hummingbird.

"The performance test didn't return any results. This probably means you're on a local website (which we can't scan) or something went wrong trying to access WPMU DEV. Try again and if this error continues to appear please open a ticket with our support heroes"

Because of this, I'm unable to act on any optimizations to improve the slow page load of my site.

Any ideas why Hummingbird isn't working?

Actually, I take back what I said. Looks like it finally worked on this latest attempt.
