dns configuration in the server is broken. As message says, no DNS 
server could be reached while attempting to get the IP address of 
destination, therefore forwarding fails.

You can check it using dns tools on the system.

Not sure how is your architecture, but registers should be handled 
locally without forwarding -- you can set alias in config file to match 
hostnames as local domains.

Cheers,
Daniel
