Host Not Found > No such host is known

The Domain Name Server (DNS) cannot resolve the named host or Internet address. Basically you are trying to connect to a site which does not exist anymore or is down temporarily. Try again with a different domain (correct) name or address.

It can also be that you need to configure SmartFTP to work with your firewall or proxy. You need to ask your system administrator or ISP for details. The problem is related to the one described in following knowledge base article:
KB: Connection refused

Finally as a test, you can try connecting to a major site like "ftp.microsoft.com". If you can connect to that  site then you know it is not a DNS configuration problem.
