Errors when I try and run a site speed check etc via Hummingbird.

Hi I keep getting errors indicating that WPmudev cannot connect to my site. I had issues linking them yesterday when I joined, and found it was a plugin conflict (effectio dashboard), but that is still off and im still having issues.
Eg:

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
