What DNS servers are you using?
Are you able to ping the site?
Have you tried removing utorrent completely and re-adding it to your firewall?
Are you using any peer blocking apps/ plugins?
I cant ping it now as I am on the road, I will try later.
We use opendns, I tried a totally different torrent client last night and had the same issue, and it does not use the files from utorrent. I have no peer block apps or plugins installed.
we use opendsn as we can get reports of usage etc. I have been using opendns since I have been with afrihost and never had issues. I did try the Afrihost dns, and there was no difference.
