[squid-users] Unable to forward this request at this time

Hi,

I am trying to access the internet using my Proxy Server
http://192.168.22.6:3128, but when I hit any page, I got

The following error was encountered:

* Unable to forward this request at this time.

This request could not be forwarded to the origin server or to any parent
caches. The most likely cause for this error is that:

* The cache administrator does not allow this cache to make direct
connections to origin servers, and
* All configured parent caches are currently unreachable.

Would someone please give me a few pointers? I used all default settings
from the squid.conf and only made changes to the following options.

Regards,
Norman
