[Hummingbird] Humming Bird Pro cant scan a site.. site extremely low

Im trying to optimize a really important site for one of my clients... it takes up to 30 seconds to load!
Im stalling the core plugins like smush, hummingbird and smartcrawl, smush is taking a lot of time to optimize and hummingbird cant scan the site...

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

The site is not on a local enviroment :disappointed:
