Hummingbird Performance Test fails

My hosting provider, eapps, has migrated me to a new server. I have been testing various things, including within Hummingbird. The following is true for all sites on my subscription (I did verify that my subscription status is active).

When I run performance test I get: “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.”

I have tried and retried on all sites under my subscription, I get the same result.

What am I missing?

Best Regards
