[Unbound-users] Strange lookup error

Hi all,

we've got here a little problem with resolving single domains. Two examples:

   ~# host www.oas.com
   www.oas.com is an alias for www.lb.oas.com.
   www.lb.oas.com has address 200.230.27.19
   ;; connection timed out; no servers could be reached
   ;; connection timed out; no servers could be reached

Or:

   ~# host www.lchclearnet.com
   www.lchclearnet.com is an alias for www.wip.lch.com.
   www.wip.lch.com has address 195.246.229.8
   ;; connection timed out; no servers could be reached

Any idea why we get an ip but the lookup itself fails?

Infos about our environment:

- Ubuntu 12.04 LTS
- Unbound v1.4.16-1
- Squid Proxy

If we try to access these domains through the proxy we get an dns error.

Thanks
Mathias
