DNS Caching Issue For community version

[Mihai Vintila]

Have you also checked that the DNS returns the correct value? As the 
valid option means that nginx will ask the DNS server again, but if the 
DNS replies with same old ip.. Also you might check using directly the 
hostname as it might be possible that there is a bug when using variables.

Best regards,
