I'm uploading my site using the built in FTP agent. I put in the hostname (hoc.org.uk), the username and the password. I get an error which says "host name does not exist". Well, I know it does because I used exactly the same parameters using Filezilla and that worked.

So, I ignore the error and click "Publish" and it all works OK and uploads my files.

What's going on?
