It would help to post the following:

#ifconfig eth0

Validate that the Static IP Address is in fact assigned to your virtual machine.

It's quie possible that due to a typo or error the static IP address never binded properly to your Ubuntu Instance. You did mention that upon initial install DHCP was able to acquire an IP Address, so we know the network is working.

Just as a quick test try doing the following:

Example:

#sudo ifconfig eth0 down
#sudo ifconfig eth0 192.168.1.55 255.255.255.0 192.168.1.1
#sudo ifconfig eth0 up

First set of octets is going to be your client IPADDRESS

Second set is the netmask

Third set is the gateway

That should temporarily set up eth0 with a static IP. Does that happen to work?

In the meantime please post the output of the following commands in a pastebin.ubuntu.com link

#ifconfig eth0

#cat /etc/default/interfaces

#dmesg
