And I was suddenly able to get the default Apache page instead of 503 varnish error, and I was able to go to staging02.cherry.com/test.php. So I am thinking there's something wrong with the above config. What can I remove in that config and what values should I enter? I am thinking ServerAdmin is wrong, I should change the IP address among other things, but I am not sure if it would work. Should I remove all ifModule configs? If it worked with simpler VirtualHost settings can we rule out a problem with php-fpm and fcgi?
