FTP error - can't login via Filezila/Dreamweaver

Hi, I’m totally unable to connect to my website I’m building via the FTP.

The first page that come with a new registered client.

It shows:

Status: Connection attempt failed with “EAI_NONAME - Neither nodename nor servname provided, or not known”.
Error: Could not connect to server

and via Dreamweaver too I can’t login to my website or upgrade it.

Here’s my info;
FTP Username epiz_24863776
FTP Password ************
FTP Hostname ftpupload.net
FTP Port (optional) 21

I’m always using them trying to getting access to my website… should I tried something else? Thanks for your time!

Try to connect to with the same credentials and the same FTP client you used to connect before and see if it works.
