[Hummingbird] The performance test didn't return any results.

Good evening,

We are currently using your plugin "Hummingbird Pro" in one of our sites, it seems impossible to measure the performance of our website and requests If there is any toruble to open a support ticket. The error continues to appear no matter what we do. We will grant you access to the website from dashboard support in order for you to fix it.

Thank you in advance. The following text is the error we're continously getting:

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
