I am using addon domains for my proxy network, although when I type in a url on any of the addon domains I get the following error: "URL Error (2): An error has occured while trying to browse through the proxy. Failed to connect to the specified host. Possible problems are that the server was not found, the connection timed out, or the connection refused by the host. Try connecting again and check if the address is correct." Any help?
You using PHProxy? I had once that problem too, I guess it's just because the remote host couldn't be reached or down. Did you try other URLs through the proxy? Did they work?
