dansguardian não estar nem com restartdansguardian.py

pessoal me deparei com um erro hoje de manhã num cliente de não conseguirem navegar na internet dando o seguinte erro;

ERROR

The requested URL could not be retrieved

While trying to retrieve the URL: http://www.google.com.br/

The following error was encountered:

Unable to forward this request at this time.

Sorry, you are not currently allowed to request:

http://www.google.com.br/

from this cache until you have authenticated yourself.

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.

Your cache administrator is webmaster.

já tentei de tudo para tentar inicar o dansguardian e não estou conseguindo alguem já passou por este problema como resolver

obrigado
