I was experiencing a similar problem as described by submitter.
The name resolution of the short name failed, subsequently the name resolution of the fqdn also failed. After 10-15 seconds, the fqdn resolved again, only to fail again after trying the short name.
The solution described by Thomas Hood:
sudo kill -HUP $(pidof dnsmasq)
resolved this issue for me. It is unknown to me how dnsmasq got itself into trouble.
