Mac Os X Lion vhosts apache timeout

after upgrade mac os x from Snow Leopard to Lion my vhosts dont respond for request – timeouted browser

after many hours and read many solution with dns and any others vhost still dont respond…

for me solution was very simple set listen

from

Listen *:80

to Listen 127.0.0.1:80

or change port

Listen *:81

and update ports for vhosts
