Hello. I’m trying to add a subdomain “dev” to my site which is running on Ubuntu 12.04x64
I had spent a few days to do this, but without any result. Only “This webpage is not available.” error.

Here is a zone file showed in https://cloud.digitalocean.com/domains/ubium.ru

$ORIGIN ubium.ru.
$TTL 1800
ubium.ru. IN SOA ns1.digitalocean.com. hostmaster.ubium.ru. 1424702134 10800 3600 604800 1800

Here is apache2.conf
