Nginx PageSpeed i get connection refused using keycdn ssl

i use shared ssl because of the benefit of using spdy but unfortunatelty i get connection refused and most js script doesnt work.
when i disabled keycdn ssl it works just fine :S
i guess i get the connection error when my https cdn url is some reason retrieving fontawesome on my domain that is https when i have ssl disabled :S any reason how i can avoid this or do i have to use https on my domain ?

 

i uninstalled centminmod, it caused conflict with directadmin :/
