I have a fantastic webfusion VPS, but suddenly this error appeared. Despite trying to re-create the files automatically, the error persisted.Thankfully, an amazingly helpful person at Webfusion support called Adam sorted it out. The reason for the error is nothing to do with the VPS, it is caused by an error in the hardware provisioning script. The hardware team can update the script, and hey-presto NGINX works again with the IP v6 address.
