Hi there,

seems like the file you request is unavailable on the remote server.

Could you run to make sure the the file is accessible:
% curl -v http://10.122.0.3/ipbl.txt

While I'm here in the configuration file you provided the backend desribed
with a hostname, not an IP address. Is there any specific reason to do that?
