It could be that the host you are trying to connect to is not on-line or that there are network issues between your computer and the host. You should first confirm that you have a working Internet connection by connecting to several web sites via a Web Browser.

You should also confirm that you have the correct connection information for this host and that the server you wish to connect to is not behind a firewall.
